Precautions for Passing While Towing
Even if you're pulling a heavy trailer down the road, there may be times when you encounter slower traffic. Maybe it's a heavy piece of construction equipment or that trailer overloaded with hay that we just mentioned. Whatever the situation may be, you will probably be tempted to pass. Sometimes, passing is an appropriate action; other times, it may not be so wise.
It's true: Passing while towing requires more effort from the driver and a lot more effort from the tow vehicle. Good judgment on the part of the driver is essential to a successful (and safe) pass.
Of course, there are always going to be unlimited variables in every passing situation. These may include environmental issues like rain, glaring sunlight or even high winds, but in general, you should keep the following few key points in mind when you're passing while towing:
- Signal early: When you're towing a trailer, it's a good idea to signal a little earlier than you normally would simply to alert the other drivers around you to exactly what you're up to. Ideally, they'll give you the extra room that you need to complete your passing maneuver.
- Pass only on level ground: Never attempt a pass while towing on an incline or steep descent. Remember, you're pulling a significant amount of trailer weight behind you, and your tow vehicle won't behave the same as it does when there's no camper or boat attached. Trying to accelerate around slower traffic as you climb a hill may leave you stuck beside the vehicle that you're trying to pass. Attempting a pass on a steep decline may lead to higher speeds that are unsafe, too. Pass only on level ground when you can see what's ahead of you clearly.
- Use your mirrors: Seeing what's in front of you is important, but seeing what's behind you can be just as important when you're passing another vehicle. Use your mirrors to make sure that another vehicle isn't attempting to pass you as you pull out into the passing lane. Your mirrors are also important tools to use to determine when you can merge back into your lane of traffic after the pass is complete.
- Make slow movements with the wheel: Ease out into the passing lane, and ease back into your traffic lane once the pass is complete. Never make abrupt movements with the steering wheel when you're passing another vehicle. Rapid movement of the steering wheel could cause trailer sway -- and you definitely don't want that.
- Regain control of trailer sway: Trailer sway can be caused by several things -- high winds, fast movement of the steering wheel at high speeds or even wind buffeting from passing vehicles (including the vehicle you're attempting to pass). No matter what the cause, trailer sway is always a little bit scary and rarely easy to recover from, so you should know what to do if it happens. First, release the accelerator, but do not brake. Braking will only magnify the situation. Keep both hands firmly on the steering wheel and allow your vehicle to slow down and straighten out. If you experience extreme trailer sway, you should activate your trailer brakes by hand. Again, don't use the tow vehicle brakes to stop trailer sway.
- Allow for the extra length of the trailer: As simple as this seems, a lot of accidents are caused by drivers simply forgetting about the extra length of their trailer and returning to their traffic lane a little too soon. Using your mirrors throughout the passing procedure can prevent this from happening.
- Be aware of your position on the road: This one is self-explanatory. Just stay alert, know what's happening all around you (in every direction) and perhaps, most importantly, use good judgment.
