A driver is traveling on a clear, dry multi-lane highway with a posted maximum speed limit of $65\text{ mph}$ and a posted minimum speed limit of $45\text{ mph}$ . The driver maintains a speed of $30\text{ mph}$ in the far-left lane despite optimal weather and light traffic, forcing several trailing vehicles to slow down abruptly and pass on the right. How do traffic laws classify this driver's speed choice?

The driver is violating traffic law by driving too slowly and impeding the normal and reasonable flow of traffic.Answer
B
The driver is fully compliant with traffic laws because driving below the maximum speed limit is always legal under the Basic Speed Law.
C
The driver is operating legally as long as the vehicle's hazard warning lights are continuously activated while driving.
D
The driver is exempt from minimum speed regulations because minimum speed limits apply exclusively to commercial heavy vehicles.

Answer

The driver is violating traffic law by driving too slowly and impeding the normal and reasonable flow of traffic.

State traffic codes prohibit driving at such a slow speed as to impede or block the normal and reasonable movement of traffic, except when reduced speed is necessary for safe operation or in compliance with law. On roads with a posted minimum speed limit, driving below that boundary under clear conditions is a direct traffic violation.

Step-by-Step Solution

Evaluate the posted traffic signs and environmental conditions.

The highway has a posted maximum limit of

65\text{ mph}

, a minimum limit of

45\text{ mph}

, and ideal driving conditions (clear, dry, light traffic).

Establishing roadway rules requires comparing the driver's speed against both posted regulatory limits and current road conditions.

Analyze the driver's vehicle speed against legal thresholds.

The vehicle speed of

30\text{ mph}

is significantly lower than the posted minimum limit of

45\text{ mph}

and disrupts trailing traffic.

Driving below posted minimum limits or creating a traffic bottleneck without a valid safety hazard constitutes illegal impeding of traffic.
