How much should you reduce your speed when driving in heavy snow?

Reduce your speed by one-third on wet roads and by half or more on snow-covered routes (i.e., if you would normally be traveling at a speed of 60 mph on dry pavement, then on a wet road you should reduce your speed to 40 mph, and on a snow-packed road you should reduce your speed to 30 mph). This will help you maintain control of your vehicle.

Reducing your speed also reduces the amount of time it takes you to stop completely after an ice storm. The faster you travel, the farther you can go before stopping. If you are caught by surprise by ice on the road, you might not have enough time to slow down before hitting it.

Finally, slowing down helps you avoid hydroplaning. When water gets under your car's tires, it can cause it to lose control and spin out of control. Slowing down can prevent this from happening.

How slow should you drive in the rain?

Drive at a slower speed than you would on a dry road. Change your speed as follows: Slow down by 5 to 10 mph on wet roads. Reduce your speed by half if there is a lot of snow. Slower speeds are safer speeds when it's raining.

Driving too fast in the rain can be just as dangerous as driving too slowly. If it's very wet out or not clear enough for you to see all traffic signals, you should still drive cautiously and avoid speeding. Overexerting yourself by trying to beat the rain or wind with your car could hurt someone else or cause your vehicle to break down.

Slowing down will help you maintain control of your car. It also helps others by giving them more time to stop if they need to change lanes or try to pass you. This is especially important if there are other drivers who don't seem to be paying attention or aren't keeping an eye on the road.

If it's only slightly wet outside, you can probably go faster than usual. But if it's really pouring, stay away from the road. Living bodies are designed to deal with the weather, but vehicles aren't and you could get stuck if you use your body to fight the rain.

Fighting the wind while driving can also be extremely dangerous.

How does snow affect the roads?

Snow and ice diminish surface friction and vehicle agility, resulting in slower speeds, less roadway capacity, and a higher collision risk. Average arterial speeds drop by 30 to 40% on snowy or slushy pavement. In moderate snow, motorway speeds are lowered by 3 to 13%, while heavy snow reduces speeds by 5 to 40%. On ice, it takes only 1/10 of an inch (3 mm) of ice to cause a car to stop completely.

The amount of traffic that can use a road at one time is called its capacity. The total capacity of a highway is the number of vehicles that can travel down it at once plus any margin for error. For example, if a highway has two lanes, then it can hold twice as many cars as there are drivers. If it has four lanes, it can hold four times as many cars. Sometimes highways are designed to handle more traffic than what actually uses them, which means they are overbuilt. Other times, highways are built to fit current demand, which means they are underbuilt. In general, larger highways are more likely to be underbuilt.

Highways work on the same basic principles that guides work on a canal or river system. There must be enough depth of channel to prevent flooding during storms or other high water conditions. But there should also be enough width so that the channel is not too narrow to navigate and large enough to allow boats to pass.

These principles apply to streets as well.

When to slow down in the snow and sleet?

When the temperature is close to freezing and sleet and snow are falling, you should slow down. Remember that there is no safe speed zone to travel in while it is snowing, so pay special attention to the road conditions and how your car handles to determine a safe pace. If you feel like you're going too fast, pull over to the side of the road and stop driving until it's safe to continue.

The best way to stay safe on ice or snow-covered roads is to drive at a reasonable speed. Don't go faster than what the conditions allow, and don't try to outrun a snowstorm. The snow will find a way through any opening, so if you can see around corners, drop-offs, and other obstacles, doing so may help prevent accidents caused by blind spots.

Slowing down also helps you avoid hitting trees and other objects in the road when it's dark out. Use caution not to hit bridges or other structures while traveling at night unless they're clearly marked.

If an accident does happen, call 911 immediately. Police officers will ask you questions about the situation then send someone for medical assistance if needed. If there's no one available to give information, then state what direction the vehicles were heading before the incident and report it as soon as possible so officials can locate them from the markings left behind.
