What is the significance of a horn sounding unreasonably loud or harsh?

The significance of a horn sounding unreasonably loud or harsh primarily indicates a failure to comply with safety regulations. In Texas, vehicle safety inspection requirements include ensuring that the horn is functioning properly and is not excessively loud or harsh. An unreasonably loud or harsh horn may suggest that the vehicle is modified beyond acceptable standards, which can be problematic for safety, as it could cause disturbances or fail to serve its intended purpose of alerting other drivers and pedestrians in a concise manner. A horn must strike a balance between being audible enough to warn but not so loud as to create additional hazards or distress on the road. Thus, this condition would be flagged during a safety inspection, emphasizing the importance of compliance with established safety regulations to ensure the safety of all road users.
