California DMV Permit Test (Class C)Rules of the Road and Right-of-WayEasy
When driving on a multi-lane highway, you should typically drive in which lane to avoid impeding traffic flow, assuming you are not passing or exiting soon?
- AThe leftmost lane.
- BAny lane, as long as you maintain the speed limit.
- CThe middle lane.
- DThe rightmost lane.
Show answer & explanationAnswer & explanation
Correct answer: D. The rightmost lane.
On a multi-lane highway, the rightmost lane is generally considered the 'slow' lane or the lane for through traffic that is not passing. This helps keep the leftmost lanes open for passing and faster traffic.
Why the other options are wrong
- A. The leftmost lane is typically for passing or faster traffic, not for continuous driving.
- B. Lane choice is also important for traffic flow, not just maintaining the speed limit.
- C. While often used, the rightmost lane is preferred for general travel to keep left lanes clear.
Lane Usage on Multi-Lane Highways
On multi-lane highways, slower traffic and vehicles not passing should generally use the rightmost lane(s) to maintain efficient traffic flow.
- Leftmost lane is typically for passing.
- Rightmost lane is for slower traffic or those entering/exiting.
- Stay in a lane that matches your speed relative to other traffic.
Memory trick: Right is polite, left is for flight.
