A motorist is driving on a rural two-lane highway with a posted maximum speed limit of . The paved road suddenly transitions onto a section of loose gravel due to roadwork, but no temporary lower speed limit sign is posted. Under speed regulation laws and the Basic Speed Law, which action is required of the driver?
- AMaintain because posted maximum limits remain legally enforceable until a lower numerical limit sign is posted
- Reduce driving speed to a rate that is reasonable and prudent for the reduced traction caused by the gravel surfaceAnswer
- CIncrease speed slightly to traverse the loose gravel section quickly and minimize time spent on an unstable surface
- DCome to a complete stop before the gravel section and wait for an official pilot vehicle or traffic officer to escort them
Answer
The driver must reduce their speed to a safe and prudent level appropriate for the reduced traction caused by the loose gravel, as required by the Basic Speed Law.
The correct response applies the Basic Speed Law, which legally requires drivers to adjust their speed downward whenever road conditions—such as loose gravel—reduce tire traction and compromise vehicle handling, regardless of whether a lower speed sign is posted.
