Prior to moving a commercial truck onto the roadway, a driver conducts an in-cab inspection of the instruments, mechanical controls, and mandatory safety devices. Which of the following findings indicates that the vehicle is in a compliant and safe operational state?
- AThe power steering system exhibits approximately 25 degrees of free play on a 20-inch steering wheel before the front wheels engage.
- The oil pressure gauge rises to the normal operating range within seconds of engine start, while the cab is equipped with three reflective triangles, spare fuses, and a charged fire extinguisher.Answer
- CThe emergency safety equipment kit contains two red reflective triangles and a full pack of spare fuses, utilizing highway flares to replace a missing fire extinguisher.
- DThe power steering wheel demonstrates 15 degrees of rotational slack before resistance is felt, while the oil pressure warning light remains illuminated at idle.
Answer
The condition where the oil pressure gauge reaches normal operating range within seconds of engine startup and the cab carries three reflective triangles, spare electrical fuses, and a properly rated, fully charged fire extinguisher.
The correct response reflects standard pre-trip inspection requirements: oil pressure must establish promptly after engine start, and the vehicle must have all three mandatory emergency equipment items (three red reflective triangles, spare electrical fuses, and a properly rated and charged fire extinguisher).
