Maximum Height Restrictions on Roads & Highways

Last updated on April 27th, 2009 at 06:43 pm

When you’re driving down the road in your big RV do you get a little apprehensive when you see a seemingly low overpass or tunnel ahead? Here are some tips to help minimize the fear.

Measure the height of your RV… from the ground to the top of your air conditioner… and post the height on your dashboard so you can refer to it when on the road.

There are minimum height standards for all state and federal highways. You can be sure they’re higher than your RV.

Bridges, overpasses and tunnels that do not conform to modern standards will almost always be signed with the maximum height and other restrictions (but beware, vandals and mother nature can remove signs). Usually there will be signs well in advance of the obstruction to provide a chance to take another route.

Purchase a Rand McNally Motor Carriers Road Atlas Deluxe Edition from Amazon.com … also available at truck stops. It will list any low clearances and shows you which roads truck can go on. If a truck can make clearance, then your RV can go there also.
