A 3-minute lesson from the Colorado course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Motorcyclists have the same rights and duties as other drivers, but with little crash protection. They're smaller, harder to see, and can move faster and stop quicker than you expect.
Know the rule
Motorcyclists are entitled to the full width of a lane. They often move around within the lane to see, be seen and avoid hazards, and strong winds can push them out of it.
A two-wheeled motorcycle passing stopped vehicles in its lane, allowed only if adjacent lanes are also stopped and it can pass safely at no more than 15 mph.
The most common motorist-caused crash with bicycles or motorcycles is a driver turning left in front of an oncoming one, by failing to see it or misjudging its speed.
You're stopped waiting to turn left and see a single headlight approaching. It's likely a motorcycle, and it may be closer and faster than it looks. Wait until you've judged its speed, then turn only with a clear gap.
Check your understanding
Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
