Avoiding Low Clearance Obstructions
Avoiding Low Clearance Obstructions with a Fifth Wheel
Avoiding low clearance obstructions with a fifth wheel often means doing some trip
planning in advance. It is easy to get yourself into a very tight spot if you are
unaware of a low clearance bridge on your route.
One of the ways to avoid low clearance bridges is to use a GPS that has bridge height data built
in. The drawback to this system is that not all bridges are in the system, especially
bridges that are on small roads into state parks and back country campgrounds.
Another way is to use a Rand Mcnally road atlas that truckers use to get low bridge data on
A new device is the Giraffe G4 Overhead Collision Alert System. This device uses sonar to read the
height of an obstruction and alert you if your Fifth Wheel is to high to pass underneath.
Below is a video demonstrating the Giraffe G4 Overhead Collision Alert System.
