I know everyone on this forum drives perfect but just to let you know there's a camera at the lane that merges onto Hwy 7--motorway, coming from Sukhumvit Pattaya heading north. If you cross the v-shaped lines when merging it will trigger--see attachment. I just barely crossed over and it caught me. My fault but I was trying to get around a slower moving vehicle so I could merge into traffic.
Also there's a speed camera at km marker 4 on the same road, about half way from Sukhumvit to the first toll booth, it's on the right hand side of the road.....don't ask me how I know LOL.
And yes I know, I should be obeying the rules while driving in Thailand.
