The only that will help is huge fines and more police visible on the roads and in checkpoints really checking, driverslicense, drugs, alcohol, and inspection of blacksmoke, lights and brakes, overloading, and wearing safetybelts. For motorcycles, wearing helmets for everyone, too much noise, driving at the wrong side of the road, or more than2 on a motorcycle. How difficult can that be than only check if the tax is paid. And give high fines when they are caught and not the highest fine only .. no count every fine ... Only when people feel it in their wallet things can change
