We explore all possibilities for reducing wrong way drivers and the current solution being implemented has been shown to be most effective and safest way.

Spike strips or tire puncture devices are not approved for use on highway ramps. These devices are meant for low volume, and low speed areas.

Research also shows that tire puncture devices do not stop vehicles traveling at high speeds from entering the highway the wrong way. Physically disabling a vehicle’s ability to move, such as upon entering an off-ramp the wrong way, may also place motorists in danger of being hit head-on by traffic that is utilizing the off-ramp. This includes the occasional driver who turns onto an off-ramp in the wrong direction, immediately realizes their error and needs to turn around.

Emergency vehicles and first responders also access the highway from off ramps to assist motorists and answer emergency calls.

Tire puncture devices can also be clogged with dirt, debris, and other material, which could prevent them from retracting even when a motorist is driving in the right direction.

Finally, installing these devices would impact snow plowing of off-ramps.
