Hazardous conditions — Virginia Permit Test
Hazardous conditions on the Virginia permit test — 8 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When visibility drops or the road is covered with rain, snow or ice, reducing your speed should be your first response.
Every other thing a driver can do works better at a lower speed, which is why it comes first rather than last.
In bad conditions, increase your space cushion by doubling your normal following distance and turn on your headlights.
Everything takes longer on a slick road, so the gap that was enough on a dry day is now half of what you need.
Use low beam headlights in heavy fog and look for the markings at the edge of the road to guide you.
Fog throws high beams back into your own eyes, so the brighter setting makes you see less rather than more.
When rain begins, the roads are more likely to be slippery during the first half hour, because oil on the surface mixes with the water.
Oil builds up between showers and floats on the first water to reach it, so the start of the rain is the slickest part of it.
Water standing on the road can make a vehicle hydroplane or otherwise lose control. Use caution driving through it and avoid it where you can.
On top of water the tires are no longer touching the road, so steering and braking do nothing until they touch again.
Remove snow and ice from your whole car before driving, including the roof, hood and rear, along with every window, mirror and light.
Snow left on the roof slides onto your own windshield under braking, or off the back into the face of the driver behind.
On slippery surfaces, release the accelerator and apply the brakes gently. You have the most traction and control when the front tires are still rolling.
A locked tire slides wherever the car was already going, and a sliding tire cannot steer at all.
Watch for ice on bridges and in shady areas. Bridges freeze before other road surfaces do.
A bridge can be iced over while the road leading onto it is only wet, so the change arrives with no warning under the tires.
On the test
What should a driver do first when conditions turn bad?
Slow down before anything else. Every other thing a driver can do works better at a lower speed, which is why it comes first rather than last.
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
Where these come from
Every rule here is checked against Virginia Driver’s Manual, published by the Virginia Department of Motor Vehicles, and against the state code itself. Last checked 2026-09-02.
