FMVSS 114

Theft Protection and Rollaway Prevention

This Standard applies to trucks and MPVs with a GVWR of 10,000 lbs. (4,536 kg) or less. However, it does not apply to walk-in, van-type vehicles. It specifies requirements for a key-locking mechanism that prevents starting of the vehicle and either locks the steering, transmission or both. It also requires a warning signal
when the key is left in the ignition and the driver’s door is opened.

Applicability:

Trucks & MPVs 10,000 GVWR or Less Yes
Trucks More than 10,000 GVWR No 
Buses 10,000 GVWR or Less No 
Buses More than 10,000 GVWR No 
Trailers No
