Gestures You are playing Russian roulette if you raise the middle finger to another driver. Horn Blowing Use your horn sparingly. If you must get someone's attention in a non-emergency situation, tap your horn lightly. Don't blow your horn at the driver in front of you as soon as the light turns green. Avoid the right lane if you are not turning right.
Headlights Keep headlights on low beam, except where unlighted conditions require high beams.
Dim your lights for oncoming traffic. Merging When traffic permits, move out of the right lane so incoming vehicles can merge. If your truck causes a traffic slowdown, pull over when you can so motorists behind you can pass. Displays Be sensitive about the signals you send. If a hostile motorist attempts to pick a fight, do not make eye contact.
