A 3-minute lesson from the Arizona course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Motorcyclists are more exposed to injury than car drivers. Most car/motorcycle crashes happen when a car turns in front of a motorcycle because the driver didn't see it or misjudged its distance and speed.
Know the rule
Most car/motorcycle crashes result from a car turning in front of a motorcycle, usually because the driver didn't see it or misjudged how close and fast it was.
A motorcycle's small size makes it hard to spot and makes it look farther away and slower than it is. Its single headlight or taillight gives fewer cues for judging distance.
Riders shift within the lane to prepare for turns, avoid hazards like oil, potholes or debris, or improve visibility. Don't assume what the rider will do.
A motorcycle ahead has its right signal blinking but keeps going straight past two driveways. Its signal may simply not have canceled. Wait until you're sure what the rider is doing before pulling out.
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.
What is the most common cause of car/motorcycle crashes described in the handbook?
A car turning in front of one
A motorcycle following too closely
A motorcycle running a red light
A car braking too hard
Answer: A car turning in front of one
Most car/motorcycle crashes result from a car turning in front of a motorcycle, often because the driver didn't see it or misjudged its speed.
Under what conditions may a motorcyclist legally pass a stopped vehicle in the same lane and direction (lane filtering)?
2+ lanes, limit 55 mph or less, cycle 25 mph or less
Any stopped traffic, cycle 15 mph or less
2+ lanes, limit 45 mph or less, cycle 15 mph or less
2+ lanes, limit 45 mph or less, cycle 25 mph or less
Answer: 2+ lanes, limit 45 mph or less, cycle 15 mph or less
Lane filtering is allowed only when the street has at least 2 adjacent lanes, the posted limit does not exceed 45 mph, and the motorcycle does not exceed 15 mph.
