A walk-around safety inspection of a heavy-duty truck's multi-leaf spring assembly reveals that 3 leaves out of a 10-leaf pack are fractured completely across. Based on commercial motor vehicle safety standards, what is the required determination for this vehicle?
- AThe vehicle is permitted to continue in regular service because the main top leaf remains intact and aligned.
- BThe vehicle may operate under a temporary speed advisory if the remaining unbroken leaves carry axle loads evenly.
- The vehicle has a critical safety violation exceeding the 25% broken leaf threshold and cannot be operated until repaired.Cevap
- DThe vehicle requires an advisory log entry for the next scheduled routine service without restricting immediate use.
Cevap
The vehicle has a critical safety violation exceeding the 25% broken leaf threshold and cannot be operated until repaired.
Commercial vehicle safety regulations state that if one-fourth (25%) or more of the leaves in any leaf spring assembly are missing or broken, the vehicle has a critical out-of-service safety violation and must not be driven until repaired. In a 10-leaf pack, 3 broken leaves represent 30%, which clearly surpasses the 25% maximum limit.
