Sharing the Road and Traffic Laws
Sharing the Road and Traffic Laws
This domain tests how a large vehicle interacts with motorcycles, bicycles, pedestrians, school buses, emergency vehicles, and work zones. The exam emphasizes blind spots, stopping distance, and giving others room.
Core rules
- CMVs have large no-zones on both sides, directly behind, and in front. Do not tailgate, and do not assume a smaller vehicle can see you. Motorcycles and bicycles can stop quickly and may be hidden in blind spots, so increase following distance and pass with a full lane change.
- Obey traffic signals, signs, and right-of-way rules. Yield to pedestrians in crosswalks. Stop for a school bus with flashing red lights unless divided-highway rules exempt you. Move over or slow down for stopped emergency, tow, and maintenance vehicles as required.
- In work zones, reduce speed, obey flaggers, and leave extra space. Use turn signals early and check mirrors before every lane change.
Worked example
A CMV follows a motorcycle at about two seconds on a dry road. The motorcycle can stop much faster than the truck. The driver should increase the gap to at least four seconds and avoid crowding the motorcycle's lane. Reasoning: the truck's greater stopping distance makes a short gap unsafe even if the motorcycle is traveling at the same speed.
Traps that cost marks
Assuming a truck can stop as quickly as a car or motorcycle; passing a bicycle without room; ignoring school-bus red lights; and failing to slow down or move over for roadside workers.
