Turns, Lanes, Passing & MergingStandalone practice
You drive a passenger car without a trailer on a two-lane highway, one lane each way, posted 55 mph. Outside a construction zone, you can lawfully pass on the left a vehicle going below 55. What temporary allowance may apply?
Correct answer: Up to 15 mph over the limit while making the pass
Why
The limited allowance applies to a passenger car, motorcycle or pickup not towing another vehicle, passing traffic traveling below the posted limit. On this one-lane-each-way road, the posted limit must be at least 55 mph. All other laws still apply and construction zones are excluded. Return right and reduce to the posted limit as soon as practicable.
