Honking is illegal in every situation

Answer: B — It can startle the rider into a crash

Honking near a bicyclist can startle the rider and cause a crash, so drivers should simply pass with adequate clearance instead.

A highway with a posted limit over 55 mph
A street with at least two lanes in the same direction and a posted limit of 45 mph or less

Lane filtering is only allowed on a street with at least two lanes the same direction and a posted limit of 45 mph or less.

7. A car driver wants to share a lane side by side with a motorcycle ahead in order to get past a slow spot in traffic faster. Is this appropriate?

Yes, as long as there is enough room beside the motorcycle
No, a motorcycle is entitled to the full width of its lane
Yes, if the motorcyclist waves the car through

Answer: C — No, a motorcycle is entitled to the full width of its lane

A motorcycle is entitled to the full width of its lane, so a car should never crowd in beside one.

About the same
About three times as long
About twice as long
Half as long

Answer: C — About twice as long

0.75 seconds
