Motor Cyclists Beware.

[NoshowJones]

A pcx150 outpace a truck, what? I have done over 170km/h in my truck on the toll ways sometimes, so I don't think so. I have a 100% standard Ranger 2.2 so nothing fancy.

I also has a pcx150 and it's very good for city riding but I don't like riding it out on the highways at it's app max cruising speed 80km/h, you are getting overtaken by most 4 wheelers. Sure you can ride at about 100km/h (full whack) but it's not very stable at those speeds and the engine will not last long if 100% loaded all the time, fuel cons. will also suffer quite a lot when you push it like that.

OP good to hear that nothing serious happened to you and you could complete your trip.

Get a cbr250/300cc and you can follow normal traffic without problems but it might not be comfortable for you?

I agree that a 150 cc bike will be unstable at 100kmh, the top speed I ride at is 60kmh, I think I am safer on the hardshoulder when I ride on the highway, but what do I do when there is an obstruction, ie a parked vehicle? I saw the rut on the road, I have used that road often, and that rut has always being there.

I slowed down to about 40kmh, no faster, and I never expected that to happen. I keep wondering what more I could have done apart from stopping and edging my way on to the first lane.

When i said truck I meant the multi-wheeled heavy trucks not a Ford Ranger or Toyota Hilux.

To me 60kph is too slow to be safe. Keeping up to the speed of the traffic or faster is safer IMO very few vehicles will pass you. Yes maybe a PCX150 isn't completely stable at 100kph but surely 80-90 is fine and big trucks wont be passing you. I have ridden my 110cc scooter long distances and it's fine doing 80kph, it could reach 100kph but I wouldn't cruise at that pace. I don't recall any heavy trucks overtaking me.

What could you have done better? From what I have read and experienced is that when you brake it adds weight to the front of your bike, so when you went over the rutt it threw your front wheel out and you lost control. It would have been better to accelerate as you went over the rutt, as then your front wheel becomes lighter and will go over the rutt more easily giving you more control.

Please read my post #30.

[NoshowJones]

Possum, i really do all i can to keep myself safe. And after testing things out i decided that i need a bike that can do at least 120kmh to be safe. A bike doing only 100kmh doesnt fit for me, as i think its dangerously slow. Too many cars coming from behind pushing you on the hard shoulder. And once you are on the hard shoulder you often have to slow down to 50-60kmh. So if you have a bike that can do 100 you can only do 50-60, if you have a bike that can do 120 you can do 120. Maybe you should upgrade to a Forza for riding highways. Imo safer and more fun than pottering on the hard shoulder.

I agree with you, there should be someone who is reponsible for such dangerous road conditions. But TiT, we should be thankful that there is now tarmac on most streets, even in remote areas. Thinking a country like Thailand can do it like a western country or even better is expecting too much. Even a country like germany is hardly able to keep all streets in good shape. Its a matter of having the money or not. For perfect streets you need much much more money.

Wantan, I think there is another reason, why is there not much much more money? Think about it.

[NoshowJones]

Glad nothing very bad happened. Forcing scooters to ride on the hard shoulder is sure a thing that should be changed. But hey TiT, and it will not change. Same as the dangerous road conditions. This is why i prefer a "bigger bike" like my CBR150 for longer rides. If i go over 100kmh cars/trucks accept me as a road user and dont force me to go out of their way. Of course i have to wear proper gear for going faster than 100kmh. Hard shoulder is pretty dangerous. Everything can happen there. I saw holes 2 meter deep without a warning sign, i saw all kinds of stones and crap laying around, cars coming the opposite way without looking at small bikes is their way, dogs sleeping, whatever.

What does it mean "small bikes are meant to use the hard shoulder"? What exactly is a "small bike"? And who is responsible for accidents that happen because the hard shoulder is dangerous? I do not believe this. As soon as you go faster than 50kmh you should use the normal lanes. Everything else is much too dangerous. It cannot depend on "small or big", it must depend on how fast you go. And 70kmh should be enough to use the left lane of the road.

Your last sentence is spot on, but 70kmh isn't enough for the first lane, because of the tailgating big trucks.

[NoshowJones]

If im on the PCX going into town I normally drive on the side hard shoulder unless i come to some uneven parts i pull out into the first lane of the 2 lane highway into town, I try to put myself into the mid part of the lane, my thinking is any passing vehicles would be forced to the outside lane to overtake,, normally drive the pcx on the highway around 100kmh + depending on conditions obviously... glad you came out of it ok possum

Thanks mate, nice to hear from a fellow Scot.

[NoshowJones]

I only ride on the hard shoulder if it is clear ahead and then give myself plenty of time to move out when I see something that looks anything like a problem. There are lumps and bumps in the road too, so it don't make much odds.

The "keep left" law here doesn't get enforced so as far as I am concern it doesn't exists, I ride where I think it is safest at all times.

200baht fine is in no way a sanction worth anything at all.

Anyway glad you are Okay mate.

That's what I did. I was the only one on the road, if I did anything wrong it was not stopping at the obstruction, and coaxing my bike on the the first lane before I arrived at the obstruction. That's what I did the rest of my journey home.

Listen mate, I am not and would not criticise anyone's driving in this situation, we are all doing our best out there. The point I am making is about the law and that if it isn't enforced it doesn't count and even if it were enforced I would still do things my own way in order to stay safe. The fuzz here don't always have my own personal safety in mind.

One day I will get stopped and fined for going through the underpass, so what, I will still continue until they make the alternative safer.

Thanks for sharing your experience, I for one will store it in my memory bank for another day hence.

Great post mate, everything you have said is spot on.

[NoshowJones]

Sorry to hear about your fall but glad that you are ok.

You mentioned previously that you think riding on the hard shoulder of the highway at 60 Kmh on a PCX is much safer than doing 130 Kmh on a big bike on the first or second lane in average traffic.

Do you still feel the same?

Thanks for your kind words, but yes, I do feel the same except for the Highway 117, for more than 30 Ks when you come near to Phitsanulok. It is the same in both directions. The road is done like that deliberately, I just can't think why.

[NoshowJones]

I don't ride on the shoulder. I tend to stay in the left lane unless passing. I am just about to ride back home from BKK. It's a lovely ride.

That's what I would do if I was riding a big bike.

[moe666]

Good tha you were noy badly hurt. I guess you have never ridden on highway one some of the ridges created by the trucks can be up to 6 inches deep, I know because I came off my bike doing about 50kph approaching a stop light. I do not blame anyone but myself for not being 100 percent aware. I could blame the truck drivers or the highway department but I was the one riding my bike and I was the one without complete awareness. Yess it would be nice if the highways were in perfect condition but I think that might happen in my next life time. But until the roads are perfect I am the only guy who really cares about my safety and I have to take full responsibility for my riding.

A safe ride is a happy ride

[NoshowJones]

In which direction are you heading from Bangkok? I bet it's not the road north to Nakhon Sawan, as you leave Bangkok on the highway, it has not long been resurfaced, the hard shoulder is ignored, and the three lanes are four or five ins above the hard shoulder.

I think we all know this is to save money, but the saved money? I think it is obvious where it went.

[ToddinChonburi]

Glad to hear you are OK, yes this is on many roads. Sometimes the run a new patch along the lane and leaves a ledge from shoulder to lane. Very Very dangerous even for cars. Always need to be aware of the surface of road you are traveling on, cracks or uneven concrete can be very deadly. Be safe.

[ToddinChonburi]

In America they love to put a line of gravel just off the hammer lane, small strip of tar then gravel. Have seen many one car accidents from people not paying attention and sliding off pavement onto gravel. They panic jerk the wheel and car goes into skid and flips. Everything inside of car not belted down gets rejected. Many times the people inside.

Ride safe !!!!!

Good post Moe, but the rut that sent me of my bike was put there deliberately, and I thought it was normal, the rest of the highway and hard shoulder for about sixty Kilos on both sides are fine.

What size of bike do you ride? If Highway one is the one to Nakhon Sawan, and I believe it is, then I have ridden and driven that route quite a lot, the first lane is exactly as you say it is.

Anyway, keep safe.

Thanks Todd, but this is a road which has not been resurfaced recently, it is in very good condition, and it is not uneven, and has no cracks, it is a continued app one inch rut that lasts for over 30 Ks on both sides of the highway.

You say you ride at 60ks , I too have a PCX 150 and go along at between 8o & 100Kph. I never use the inside 2 way traffic lane, too many sleeping dogs ,too many parked cars an folk likely to pull out from the side at any moment, Get in to the first lane and go faster.

[dotpoom]

Glad you're OK, a frightening experience.

[Liquorice]

Unless you ride a smaller bike, some of the road conditions may not be obvious.

I've had problems getting stuck in a rut, back wheel jumping and skidding over 'cats eyes' and once hit a deep pothole which was covered by water during rain.

The bike stopped but I continued straight over the bars. Luckily I was only going slow. A couple of scrapes and bruises.

Wider tyres would eradicate some of the dangers and I believe they are available for certain models.

Speed kills!

On these roads and the guarantee that you can expect the unexpected from other road users, I've never gone above 70kph, even then I wear brown trousers and swear a lot.

Not a big bike. Am 1/2 way home from BKK to Nakhon Nayok now.

The nice thing is, I have passed through 6 police checkpoints and have been waved through each time. They are stopping everyone but me. They see the stickers, smile and salute.

Life is good

Interestingly, in Taiwan a 150cc bike is classified as "Huge, big bike"

I cannot agree about your 30mph (50 kph) - or driving-in-town speed - on the normal lanes of the open-road.

Are you talking about the inside lane on a road which has no hard shoulder, but not in a built up area?

To me, that all depends, Thai law says you must always ride to the left, if I don't agree with anyones rules or laws, then I do not obey them, if I do, then I may as well just stay in bed.

That means I do not always keep to the left for the very reasons you state, it you are going to do a U turn or right turn further up the road, the you have to move in to the right lane

in plenty of time, otherwise the traffic won't allow you to make the right or U turn further up the road.

There is one prominent poster, to this forum, though not on this topic who villified me for saying this.

I have to say though I think you are riding far to fast if there are places where traffic or pedestrians, or dogs may come out in front of you, your vision being blocked by parked cars, that would also apply if you had a big bike.

Also, riding a PCX150 at 80Kph maybe, but riding at 100 Kph, the bike I think would be a bit unstable. Just my opnion. Anyway. Keep Safe.

[Tomtomtom69]

Confused that you ride a bike on the hard shoulder and not on the first lane which is meant for slower traffic, if at all slower traffic does exist within thailand.

Sorry for the pun but glad to hear you came out of it relatively unscathed.

Thanks mate, but smaller bikes are meant to use the hard shoulder, they are even allowed to go up them the wrong way, it says so in part of the motor cycle test.

Besides, using the first lane will just get you tailgated by all the big trucks, how dangerous would that be?

Are you sure motorcycles are "allowed" to travel the wrong way on hard shoulders? I know they do so on a daily basis, but as far as the legality is concerned, that would shock me. Surely it can't be legal, even if it shockingly allowed to occur, on a daily basis throughout the country?

[Tomtomtom69]

Sorry to hear of your accident and I'm glad you're ok but..

You knew of this rut for a long time and yet it''s not your fault at all? Yes it shouldn't be there but you are partly to blame for knowingly riding on an unsafe part of the road . Hard shoulders are commonly filled with rutts and potholes. It is perfectly legal for bikes to use the left lane.

You get tail-gaited by trucks and doing over 70kph is dangerous? Come on a PCX150 will easily outpace any truck and is super comfy at speeds over 70.

You should be in the left lane not on the hard shoulder. If you need to move onto the hard shoulder to let something pass you then do it but after move back onto the left lane.

After reading this, if you cant handle speeds over 70kph on a highway, then I think you are a danger to yourself, other road users and should stick to cars or pottering about in your village.

Good point, but when has the legality of something ever been an issue in Thailand? We all know about the dumb motorcyclists who ride along the hard shoulder going in the opposite direction of the traffic flow, but the OP even suggests that is legal. That is mind-boggling. I'm not saying he's wrong as I've done the motorcycle test too but I can't for the life of me recall that question being on the test. What I think is logically it's not legal, but a blind eye is turned to the practice. Similarly, you can drive in the left lane, right lane, wherever you want even at a low speed on a motorcycle, nobody is going to give a crap BUT you may find yourself injured or worse as a result. It's every man for himself out here, that's the reality.

It seems to me that Wantan is saying that when he goes faster than 50Kph, he moves out to the first lane.

I do agree that 70Kph should be fast enough on the inside or first lane, but in this country full off halfwits driving and riding, I would not want to be going at 70 Kph

on the first lane.

I would think that a big bike would be OK doing say 120 Kph on either lane, depending on traffic conditions and the state of the road, although there is always a chance

of someone coming out of a small side lane without looking, but the same could apply on a PCX150 doing say 50 Kph, but the PCX rider having a much better chance of surviving.

I have just found out from the Thaivisa lawyer that it is not legal, as you say, but a poster did say that according to the theory part of the motorbike test, at some test centre, it was lawful.

That sucks- glad you made out as well as you did. Hitting that kind of a rut can be (obviously) a real disaster- the effect is instantaneous and you have very little chance to escape it once you find yourself in it. What was it- quick monster head-shake and then down?

Yes, I had to but the saddlebags back on, also the big bag tied in front of my topbox.

This was the last stage of my road trip to Maesot for visa, then to Phitsanulok.

I am seriously thinking about giving up those road trips, only because of Thailands roads.

In the road trips I have done so far, I have seen many idiot drivers and riders, but never

had any altercations with anyone, and no near misses.

Only problem being the roads. I doubt if any country would allow roads like that

for years and do nothing about it.

Agreed.

I doubt if any country would allow roads like that

for years and do nothing about it.

You guys obviously haven't been to Egypt, or just about every other country in Africa!

Having said that, thanks for the timely warning. I'm just about to buy my first M/C in Thailand and my first since 1978! Slowly and carefully does it and no night riding until I get to know the roads well.

Yes, I too would not ride in the hard shoulder. I've encountered pedestrians, M/Cs going in the wrong direction and even a ten wheeler out on route 22 near Udon Thani.

Glad to read that you came out of it relatively unscathed Possum.

[Lee4Life]

Sorry for the pun but glad to hear you came out of it relatively unscathed.

You stand a good chance of being run down on a small bike if you make a practice of using the first lane here. I ride a big bike and am usually doing around 100kph or more on open multi-lane roads, I use the first lane a lot instead of the shoulder to avoid smaller slower bikes, pedestrians or such. I have had a few close calls with cars and trucks who's drivers make it obvious that they think I should not be using that lane, but should be on the shoulder. It is not uncommon for them to come alongside and run me over onto the shoulder. If it is night time they will come up from behind and start flashing their headlights at me to get over and let them pass...even though all other lanes are empty.

I have learned to deal with it by staying as alert as possible to those people and often adjusting my speed down and pulling onto the shoulder.

[PattayaPhom]

Isn't what everyone referring to as the hard shoulder in fact the bike lane?

[Moonlover]

Isn't what everyone referring to as the hard shoulder in fact the bike lane?

It really is good to get some input on this topic from experienced riders here. Pattayapom, I have noticed roadside signs that would seem to suggest that you are correct on this issue, but I cannot read Thai and as we flew past them quickly I wasn't able to ask my wife or driver what they meant. I shall make a point of doing so as soon as I can and report my findings on this thread.

[Dogbreath]

What you encountered is a hazard motorcyclists throughout the world encounter on a regular basis. It is called an "edge trap" and will drop any motorcycle from a Honda Wave 100 up to a Harley full dresser. If you have to cross to another lane that is 1" step or more higher than the lane you are in, cross at a 45 degree angle or greater and no problem. At an angle of 20 degrees or less, you and your bike are going down; hard. I know this based on experience. Google - Motorcycle Edge Trap for a more thorough explanation. Good luck and ride safe.
