Noise Complaints Prompt Feds to Drop Daylight Running Horn Proposal

The use of vehicle daylight running lights (DRLs) has resulted in a significantly reduced number of traffic accidents, according to the National Highway Traffic Safety Administration (NHTSA).

Because DRLs were so effective, NHTSA began a study to determine if adding a requirement for a daylight running horn (DRH) would lead to even further accident reductions.  

Under the DRH proposal — which applied to motorcycles, cars and light trucks — the horn would sound continuously anytime the vehicle was in gear.  

However, NHTSA announced today it has canceled the DRH program after receiving thousands of noise complaints.
