Example Use:

The 'Runaway Vehicles Only' sign (MUTCD R4-10) is commonly seen on steep mountain highways or routes notorious for causing brake overheat in heavy vehicles. For instance, consider a mountain pass in Colorado. As vehicles, especially heavily loaded trucks, descend this pass, the prolonged use of brakes can lead to overheating and potential brake failure. To combat this risk, an escape ramp—often filled with loose gravel to slow down vehicles—is constructed adjacent to the roadway. This ramp is designed to provide a controlled area for vehicles to stop or slow down in the event of brake failure or similar emergencies. Before the entrance to this ramp, the 'Runaway Vehicles Only' sign is prominently displayed. It indicates to drivers that the ramp is specifically designated for emergencies and not to be used as a regular exit or pull-off area. The sign effectively communicates to drivers experiencing brake issues that there's a nearby location to safely regain control of their vehicle.
