During inclement weather conditions, many people have commented about seeing signs around highways and freeways warning ‘high profile vehicles’ about high winds. But what constitutes a high profile vehicle?
First of all, let’s get one thing straight: high profile vehicles are NOT expensive or flashy cars. While, yes, they are pretty high profile, that’s not what ‘high profile vehicles’ mean in context. In fact, high profile vehicles are actually a specific and technical term about a specific class of automobiles that are more susceptible to sudden gusts of wind.
So, to answer your question…
What is a High Profile Vehicle?
Basically, a high profile is any vehicle that has a large, exposed surface area that cross winds can affect. This means that vehicles like trucks (from multi-wheel semis to light container trucks), trailers, and even some SUV’s can be considered a high profile vehicle.
In this context, the term ‘high profile’ refers to the large sides, or profile, of a vehicle, and NOT its personality, as some people mistakenly believe. High profile vehicles are often warned about strong winds because these vehicles are often traveling at relatively faster speeds, which means their large surface area makes them prone to being hit by sudden gusts of cross winds that could potentially knock them over.
The risk of high winds is different for each vehicle, depending entirely on their center of gravity, weight, and of course, wind speeds. However, high profile vehicles need to take certain precautions like reducing travel speed or figuring out a way for the wind to pass through their sides.
In the U.S., individual states have differing laws that govern whether or not a high profile vehicle can travel during inclement weather; some states can even issue travel bans on high profile vehicles if the winds are strong enough.
What Do High Profile Vehicles Need to Worry About?
As mentioned, there are a few factors that govern what constitutes as a ‘risk’ to high profile vehicles. Of course, a slight breeze or barreling down the freeway won’t exactly turn your SUV into a makeshift rollercoaster, but even gentle breezes can turn into high-speed gusts that can knock your vehicle down in no time.
What’s worse is that these gusts of wind can come out of nowhere; there doesn’t have to be a storm or a snow flurry to create strong winds that slice across the freeway. In fact, despite clear skies and a sunny day, high winds can be just as dangerous for high profile vehicles as hurricanes.
High winds are defined as gusts of air that are over 30mph or above 50kmh, or a 7 on the Beaufort Wind Force Scale. On the highway, high winds can pose more than its fair share of troubles:
- Strong winds can blow various forms of debris onto freeways, from tree branches and small pieces of gravel to tarps and loose man-made objects. These objects, while harmless on their own, can be extremely damaging when run over at fast traveling speeds.
- If the wind is strong enough, it can knock down small trees and bushes from the side of the road and onto the highway.
- High winds can kick up dust and dirt, lowering visibility and increasing the chances of debris hitting your windows and windshields.
- High profile vehicles with narrow sides can easily be knocked over while traveling.
- High winds coupled with rain are even more precarious, with high profile vehicles becoming more susceptible to losing control while traveling at even moderate speeds.
Driving Your High Profile Vehicle Safely During High Winds
When driving your high profile vehicles during high winds or other inclement weather, it’s best to treat it like winter conditions; stay on the lower gears for more torque, ease up on the accelerator, stay as alert as possible, and be ready to do some defensive driving should you lose control. Other things you can to drive your high profile vehicle safely during high winds:
- Look out for weather reports! The U.S. National Weather Service regularly puts out weather advisories whenever high winds are present in a particular region. Usually, the U.S. National Weather Service will introduce a High Wind Watch if there are sustained winds of 40mph and above, or if they’re expecting high winds in the next 12 hours.
- Practice basic driving safety! Hold the wheel firmly with both hands in the 9 and 3-o’clock positions, the recommended technique by the National Highway Traffic Safety Association. However, if your vehicle has a large-diameter steering wheel and has no airbag, the10 and 2-o’clock positions are better.
- Stay well below the speed limit! It’s there for a reason, ESPECIALLY during inclement weather conditions. In fact, during high winds, it’s better to stay as close to the minimum speed limit as much as possible. This increases your chances of staying in control should a strong gust of wind hit your high profile vehicle.
- Turn on your headlights if the winds kick up dust. Low visibility coupled by unchecked speeds is a surefire way to get into an accident.
- Be wary of other high profile vehicles, especially the ones towing cargo like 18-wheelers, tow trucks, or trailers. Sudden wind gusts can knock cargo off of these high profile vehicles and instantly turn the road into a dangerous obstacle course.
- Watch out for foreign objects that are littering the road. Again, small objects might seem harmless, but running one over can have unintended consequences, like having that object thrown up into the air and onto the car behind you, or worse, puncturing your wheels and spinning you out of control.
- If you find yourself caught in a side wind, remember: steer in the opposite direction. Be gentle when turning the wheel, as sudden jerking movements can cause you to spin.
- Head winds and tail winds can be easier to deal with as they have less of a chance of knocking your vehicle on its side. Given that, however, be alert anyways: if strong tail winds are pushing your vehicle faster, ease up on the accelerator and DO NOT use your brakes to slow down, as this can cause your vehicle to spin.
As always, always be safe when driving, be alert and be courteous to other people on the road, especially in a high profile vehicle!
