Turns, lanes, passing and parking
You are towing a trailer on a highway with four lanes in your direction and no lane marked for slower vehicles. Which lanes may you use?
- Only the two lanes closest to the right edge. Correct answer
- Only the lane farthest to the right.
- Any lane except the one farthest to the left.
Why
The towing rule has two layers. Normally a vehicle pulling a trailer, and likewise a truck with three or more axles, keeps to the far-right lane or to a lane marked for slower vehicles. When there are four or more lanes in your direction and none is marked, you get a bit more room: the two lanes nearest the right edge, and only those. So the far-right-only answer is the starting rule, not the one for this road, and the answer that opens up everything but the left lane hands you one lane too many. Towing also changes your speed: the limit for vehicles pulling trailers is 55 mph.
Where this comes from
California Driver's Handbook, June 2025 edition. The correct answer is Only the two lanes closest to the right edge.
