Night Rain on an Unlit Highway
It is 10 p.m. and raining steadily. You are on an unlit rural highway posted at 55 mph, driving at 55. Your wipers are on high. Visibility is reduced, and the road surface is wet with some standing water in the wheel ruts. You are 20 minutes into a two-hour drive and feel alert but a little tense. Ahead, you can see the taillights of a truck perhaps 300 feet away. A car behind you is following closely with bright headlights reflecting in your mirrors. You notice your steering feels slightly light in a patch of standing water.
1. What does the light steering tell you, and what should you do immediately?
Read the worked answer
Light steering on standing water is an early sign of hydroplaning - the tires are beginning to ride up on a film of water rather than gripping the pavement.
The correct response is to ease off the accelerator smoothly and hold the steering wheel steady, avoiding sudden braking or sharp steering inputs. Do not jerk the wheel or stomp the brakes, which can cause a loss of control or a spin. Let the vehicle slow gradually until the tires regain contact and steering feel returns. Afterward, reduce your speed for the conditions.
2. Is 55 mph appropriate here? Justify your answer.

No. The posted 55 is a maximum for ideal conditions, not a target for rain at night. With reduced visibility, wet pavement, and standing water, the safe speed is lower - often well below the limit.
Wet roads increase stopping distance and raise hydroplaning risk, and hydroplaning risk climbs with speed. At night in rain you also have less time to see hazards. The right move is to slow down to a speed where you can stop within the distance you can actually see and where the tires maintain grip. That may mean 40–45 mph or less in the worst patches.
3. How should you handle the tailgater with bright lights behind you?
Read the worked answer
Do not react by speeding up or by braking to 'send a message' - both increase risk on a wet road. Reduce the glare by adjusting your mirror (many have a night/dim setting) and keep your eyes on your lane and the road ahead rather than the mirror.
Maintain a steady speed and increase your following distance behind the truck ahead so you have room to brake gradually rather than abruptly, which also protects you from the car behind. If the tailgater persists and it is safe, let them pass. On a wet night highway, smooth, predictable driving matters more than teaching the follower a lesson.
