Night Rain, Hydroplaning, and a Deer
You are driving north on a rural two-lane road at 55 mph at 10:30 pm. Rain has been falling for 20 minutes, and standing water is visible in the right wheel track. Your headlights are on low beam. A pickup ahead is about 2 seconds away, and its taillights are dim. Your wipers are on high, but the lower right corner of the windshield is fogging because the defroster is not keeping up. You feel a slight pull to the right, and the steering feels light. A deer steps onto the shoulder about 100 feet ahead. You have two passengers and a dog in the back seat. The road has no streetlights, and the shoulder is soft.
1. What do the light steering and pull to the right tell you, and what should you do first?

Light steering and a pull to the right in standing water are warning signs of hydroplaning: the tires are riding on a film of water rather than gripping the road. Your first action should be to ease off the accelerator and hold the steering wheel firmly and straight. Do not brake hard, jerk the wheel, or make sudden corrections, because that can cause a spin or loss of control.
Avoid using cruise control in these conditions. Let the vehicle slow gradually until the tires regain contact and the steering feels normal again. The wet road already reduces traction, and the dim taillights ahead mean you need more time to react. Reducing speed is the priority before dealing with the deer or the fogging windshield.
2. The deer is now at the edge of your lane, 100 feet ahead. What is your braking and steering plan?

Brake firmly but smoothly, without locking the wheels, and keep the vehicle in your lane. Do not swerve into the oncoming lane or onto the soft shoulder; those choices can cause a head-on crash or a rollover, which is often worse than hitting the deer. At 100 feet and 55 mph, you have very little time, and the wet pavement lengthens stopping distance.
If a collision looks unavoidable, continue controlled braking and stay in your lane. The deer may move unexpectedly, so aim to reduce speed rather than predict its path. Keep the dog secured or ask a passenger to control it so it does not distract you. After the deer is clear, do not accelerate back to 55 mph; the road is still wet and visibility is poor.
3. How should the rain and fogging change your following distance and speed, and what should you do about the pickup?
Read the worked answer
A 2-second gap is too close for wet pavement at night. Increase your following distance to at least 4 seconds, and more if visibility worsens. Slow below 55 mph so you have more time to see and react, especially because the pickup’s dim taillights make it hard to judge its speed.
Turn on the defroster or air conditioning and adjust the vents to clear the fogging corner of the windshield. If the fogging continues, pull off the road at a safe, well-lit location and clear the glass rather than driving with a blocked view. Keep low beams on; high beams can reflect off rain and reduce visibility. Maintain a larger gap to the pickup and avoid passing unless you have a clear, long view.
