You're going to encounter air resistance whenever you take your vehicle out for a drive. Automakers have to take this factor into account by improving a vehicle's aerodynamics and reducing noise caused by the wind so that the interior is comfortably quiet. Once the wind starts to become especially powerful, however, it will have a greater effect on your driving.

Whether they are accompanying a severe storm or arrive unexpectedly on a sunny day, gusts of wind can wreak havoc on travelers. Sustained winds can be powerful enough to push a tractor-trailer truck over onto its side. Earlier this year, winds knocked several railroad cars off a bridge in New Orleans.

The National Weather Service says it includes three kinds of alerts in its forecasts. High wind advisories let people know when sustained wind speeds of 30 miles per hour with gusts of at least 45 miles per hour have been recorded or are expected. High wind watches are issued when sustained wind speeds of 40 miles per hour and gusts get up to 58 miles per hour are expected, while high wind warnings indicate that these winds are occurring.

During high wind watches or warnings, the National Weather Service says drivers should postpone any unnecessary travel. It recommends that anyone who ventures out in these conditions should be prepared for sudden changes in the wind and try not to drive perpendicular to the wind direction.

If you have to travel, plan ahead for any changes resulting from the wind. Bridges may be closed if sustained winds reach a high enough speed, and roads will be shut down if they are blocked by debris.

All vehicles can be affected by strong winds, but "high profile" vehicles with a greater surface area for the wind to act on are at a higher risk. In addition to buses and tractor-trailers, the Nevada Department of Transportation says recreational vehicles, SUVs, trucks, vans, and vehicles towing trailers are more likely to be pushed by the wind.

People driving a high profile vehicle should be especially cautious during windy conditions, but other drivers should also use care when traveling near one of these vehicles. Maintain a safe following distance and be prepared for any sudden changes if a high profile vehicle is in a nearby lane. The Automobile Association, an English drivers' organization, says high profile vehicles may be unexpectedly blown into your path. They can also be pushed onto the shoulder, so it is important to wait a safe distance from your vehicle if you break down during strong winds.

In addition to pressure from the wind, your vehicle can be pushed off course by the slipstreams from other vehicles on the road. You're also more likely to be buffeted by gusts while crossing exposed bridges, traveling through open areas, or after passing a high profile vehicle. Keeping a firm grip on the steering wheel can help you anticipate these gusts and correct for them.

Slow down if the winds are strong enough to affect your driving. If you are blown out of your lane by the wind, the slower speed will allow you to correct your course more easily.

Winds may be accompanied by conditions that hinder visibility, such as rain or snow. The Nevada DOT says turning on your headlights can help you see the road and alert other drivers of your position.

During windy conditions, it is more likely that debris will be blown into the road. The Automobile Association says the presence of twigs or small branches on the road indicates that larger branches or trees could also be brought down in your path. Be especially cautious when coming around corners.

Winds can also cause power lines to fall onto the road. The Nevada DOT says the lines can still carry electricity even if they have been downed, so you should never drive over them. Instead, seek an alternate route and inform the police and local utility about the issue.

If the winds are strong enough that you don't believe you can continue safely, find a safe place to pull over. Avoid the shoulder of the road, since winds can still push other motorists into this area. You should also stay away from trees, power lines, or other objects that might be toppled onto your vehicle.
