Driving Your Car in Bad Weather: How to Avoid an Accident

Driving in bad weather is stressful at any time of year and it potentially increases your chances of getting into an accident.

Most often, car accidents that occur in poor weather is due to drivers' failures to slow down in rainy, icy, or snowy conditions. Vehicle technology has evolved over the years to make cars safer to operate in inclement weather, but you still have a responsibility to drive safely when the weather turns nasty.

At any time of the year, the weather can unpredictably make driving a hazardous affair in Canada. Driving too fast or carelessly in poor weather can lead to a collision, which is why paying attention to road conditions, and taking it slow behind the wheel when Mother Nature rages is the best way to protect yourself, avoid an accident, and the impact a collision can have on your auto insurance premium.

Here are some of the most common bad-weather scenarios that affect Canadian motorists:

Drivers must worry about more than the thunder and lightning when driving in thunderstorms. In some parts of the country, severe thunderstorms precede tornadoes. It is critical to know what to expect when driving in thunderstorms, so tune the car radio to a weather station that will give the appropriate warning of any impending tornado activity. Also, follow the rules of driving in the rain, even if the thunderstorm is a dry one. Turn on the car's low-beam headlights, slow down, and allow for extra braking distance should the cars ahead need to stop suddenly or get into an accident. If the thunderstorm becomes unruly, find a safe place to pullover away from trees, electrical poles, or any other potential falling hazard, turn off the car, and wait it out.


The best approach for driving in a tornado is not to do so. Driving during the threat of wind tunnels is a no-win situation. Even if drivers are already out on the road and the weather shifts to a tornado threat suddenly, drivers need to stop operating their vehicles. Tornadoes are highly unpredictable and can shift quickly and without warning; attempting to race away from or out-manoeuvre a tornado is too dangerous to chance. Pulling over and staying in the car is also too dangerous to chance, as tornadoes can pick up and move cars miles away. Instead of attempting to drive away from a tornado, drivers should immediately seek shelter and take cover until the tornado passes.


Horror movies have made fog scary enough without having to drive in it. Keep in mind when driving in fog high-beam headlights actually make visibility worse, so always drive with the low beams. Drivers should also crack their window a little, so they hear the traffic better – fog suppresses sound. Reduce your speed when driving in fog and keep plenty of distance between your vehicle and others in front of you. Use the road's dividing lines as a guide to ensure the car stays in the lane, and never attempt to change lanes in foggy weather. It's best to stay put and keep moving forward, slowly and cautiously.


Rule No. 1: don’t attempt to drive during a hurricane. In many cases, however, drivers might be trying to get out-of-town before the storm strikes and do not make it. When driving in a hurricane, it is critical to have a plan before the storm ever hits. Prepare an evacuation plan during the hurricane off-season by mapping and driving all available routes from wet to dry land. Keep your automobile stocked with emergency supplies, such as a first-aid kit, non-perishable foods and manual can openers, drinking water, a flashlight and batteries, as well as a portable radio and batteries, and blankets. Also, keep the car full of gas at all times and always have a fully charged cellphone. Keep the car's maintenance in check to avoid breakdowns and when it's time to hit the road, drive slowly, cautiously, and avoid all potentially flooded areas.


Winter driving is another matter altogether. Safely driving through a blizzard means being prepared beforehand. Keep your car in tip-top shape during winter months and pay special attention to the condition of the tires and windshield wiper blades – and have winter tires installed. Most insurers will give you a discount if you drive with winter tires during the colder months. Always keep extra antifreeze in the car, as well as other necessities such as blankets. Let somebody know the route you’re taking and approximately how long it should take to arrive at your destination. That will help authorities if they must look for drivers who got lost in the blizzard's low-to-zero visibility. Drive slow and keep a wary eye on all of the vehicle's gauges to make sure the car is operating properly through these very dangerous conditions. Drivers who get stuck in the blizzard should make sure the exhaust pipe is clear of snow and debris to avoid carbon monoxide poisoning.


Cars and their passengers are more vulnerable when it's raining outside. Water mixes with oil on the roads and highways and can make them slick and slippery. As with other types of inclement weather, slow down when driving in rainy weather. Driving in rainy weather requires a little patience and a lot of common sense. Drive cautiously, turn on the headlights, don't follow other vehicles too closely, and don't make unnecessary lane changes or turns. Keeping the car tires on the road helps prevent accidents, and when drivers are driving too fast or make sudden changes in direction, the car tires can separate from the road and cause what is called hydroplaning. Should the car begin to skid or hydroplane while driving in the rain, take your foot off the gas and carefully try and turn the car to right the vehicle. Do not brake if the car has traditional brakes; gently brake if the car has an anti-lock braking system. Always keep the car's maintenance up to date and the tires properly inflated to help avoid breakdowns and accidents in the rain.


The dangers of flash floods can turn a car into an unwilling boat. Use all precautions when driving in rainy weather and avoid continuing down any road that has large pools of water on it. Flooding is deceptive on roadways and is capable of sweeping a vehicle away. Do not take for granted that a car will keep everyone safe in a flooding situation. Rather, think as if everyone was on foot and head for higher ground until the flooding subsides. With flooding, and any other type of weather hazard, it's best to stay off the road. Never drive in any inclement weather unless it is absolutely necessary.

Staying Safe Behind the Wheel in Bad Weather

If you have the unfortunate experience of being involved in a car accident, you may need to file a claim. Regardless of the time of year, obeying the rules of the road, driving the speed limit, and avoiding being a distracted driver is essential for the safe operation of a vehicle.

Moreover, it can’t hurt to take a quick refresher on how to drive at night and in bad weather from the Ontario Ministry of Transportation’s Driver’s Handbook. After all, maintaining a clean driving record with no collisions can help you save money on your car insurance premium.
