The Wet Curve with a Faded Sign and a Deer
You are driving a light car on a two-lane road at night in light rain. A curve warning sign ahead is faded and partly hidden by an overhanging branch, so you see it late. The road curves sharply to the right. Your tires are about four years old with moderate tread, and your tire pressure warning light came on this morning but you have not checked the pressures. As you enter the curve, a deer steps onto the road from the left about 80 feet ahead.
1. What should you have done before the curve, and what do you do now?

Before the curve, the faded sign is a cue to slow down rather than assume the road continues straight. In rain, with uncertain tire condition, you should have reduced speed, checked that your tires were properly inflated, and been ready for the curve to be sharper than it looks. The pressure warning light is a warning, not a suggestion; underinflation reduces grip and increases stopping distance.
Now, with a deer 80 feet ahead, brake firmly and smoothly without locking the wheels, keep both hands on the wheel, and do not swerve hard into the oncoming lane or off the shoulder. Swerving at speed on wet pavement risks a loss of control or a worse crash. If you can stop short, do; if not, brake and steer only as much as needed. Deer often travel in groups, so watch for more after the first.
2. How does the wet road and tire condition change your stopping distance and your choices?
Read the worked answer
Wet pavement reduces friction, so stopping distance grows compared with dry asphalt, and worn or underinflated tires make it worse by reducing contact grip and allowing more flex and heat. At night in rain you also have less visibility, so your perception-reaction distance is longer. Together, the total distance to stop can be far greater than you would expect at a given speed.
The practical choices: slow down before hazards, increase following distance, and keep tires properly inflated and replaced when tread is low. In this moment, brake early and firmly rather than late and hard, and avoid sudden steering inputs. After the incident, check tire pressures and tread, and replace tires that are worn or damaged.
