The posted limit is 55 mph, but heavy rain and poor visibility make that speed unsafe. What should determine your speed?
Correct answer: A lower speed that is reasonable for the conditions.
The basic rule requires a reasonable and prudent speed for actual and potential hazards. A posted maximum is not a promise that it is safe in every condition.

Which circumstance supports the statute's 70-mph maximum for an ordinary car?

A multilane divided primary highway has official 60-mph signs. Under ordinary favorable conditions, what maximum applies?

A hazard makes it necessary to drive below a posted minimum speed. Does the minimum-speed rule force you to continue at an unsafe speed?
Correct answer: No; necessary safe operation is an exception.
The minimum-speed rule preserves an exception when reduced speed is necessary for safe operation or compliance with law. Do not create a hazard to meet a number.

A car is directly behind you in the far-left lane of a controlled-access highway. You are not passing, the right lane is safe and open, and no exception applies. What should you do?
Correct answer: Move to the right lane when safe.
With no applicable exception, the far-left lane is for overtaking and passing. The rule does not authorize speeding or a sudden unsafe lane change.

Snow makes the right lane unsafe while the left lane provides the safer usable path. Does the far-left-lane rule recognize this situation?

You use an opposing-traffic lane for a lawful pass. By what distance from an oncoming vehicle must you be back in an authorized travel lane?
Correct answer: Before coming within 200 feet of it.
The pass must be completed without interfering with others, and you must return before coming within 200 feet of approaching traffic. Do not begin a pass without ample visible clearance.

Visible signs and pavement markings identify a no-passing zone. May you cross its left-side restriction merely to pass a slow car?
Correct answer: No; obey the no-passing restriction.
A clearly marked no-passing zone must be obeyed. The narrow obstruction and driveway-turn exceptions are not permission to overtake an ordinary slow car.

Construction is underway, and passing another car would endanger a road worker. Is the pass allowed because a lane seems wide enough?
Correct answer: No; that hazardous work-zone pass is prohibited.
Do not overtake in a highway work zone when doing so would be hazardous to a highway worker. Available pavement does not remove this restriction.

Workers are nearby in a marked work zone. May you drive through a coned-off lane to get around the queue when there is no emergency?
Correct answer: No; use only lanes designated for traffic.
Driving through a work-zone lane not designated for traffic can endanger workers. Remain in the channel provided for road users.

On a highway with two lanes each way, a tow truck displays amber warning lights beside your lane at a traffic incident. The next lane is safely open. What must you do?
Correct answer: Slow significantly and move into the lane farther from it.
The stationary-emergency-vehicle rule includes authorized recovery and towing vehicles. Approach cautiously, significantly reduce speed and change away when safe on a qualifying multilane road.

You approach a stationary authorized emergency vehicle displaying warning lights, but traffic makes moving over unsafe. What should you do?
Correct answer: Reduce speed significantly and pass at a safe speed for conditions.
When a lane change is impossible or unsafe, maintain a safe reduced speed and due caution. The inability to change lanes does not cancel the need to slow.

You miss a destination on a divided highway. May you drive across an unbroken physical median simply to turn around?

A stalled vehicle blocks your side of a two-way road, making a move left of center necessary. Before going around it, you must:
