TX DMV Weather and Hazardous Conditions 3

Question 1

Your vehicle begins to hydroplane on a wet Texas highway. The best immediate action is to:

Accepted Answer

Ease off the gas and steer straight until tires grip

Answer

Easing off the accelerator reduces tire speed gradually, allowing the tires to regain contact with the road surface without causing a spin.

Question 2

In icy conditions, the stopping distance for a vehicle traveling at 30 mph is approximately how many times greater than on dry pavement?

Accepted Answer

Up to four times as long

Answer

Ice reduces tire friction dramatically, making stopping distances up to four times longer than on dry pavement at the same speed.

Question 3

Which Texas weather phenomenon is most likely to create a 'black ice' hazard?

Accepted Answer

Overnight temperatures dropping below freezing after daytime rain or drizzle

Answer

When wet pavement freezes overnight, the thin transparent ice layer called black ice forms and is nearly invisible against the dark road surface.

Question 4

When approaching a low-water crossing marked with a water depth gauge during heavy rain, you should:

Accepted Answer

Check the gauge and turn around if water is over the road

Answer

Depth gauges exist to help drivers assess crossing safety; any water over the road surface at a crossing is considered dangerous and drivers should turn around.

Question 5

Driving through standing water can cause brake fade because:

Accepted Answer

Wet brake pads and rotors reduce friction until they dry

Answer

Water on brake rotors and pads temporarily reduces friction efficiency, so drivers should gently apply the brakes after crossing water to generate heat and restore stopping power.
