Vehicle InspectionQuestion 13 of 120
Why is a leaking exhaust system a serious defect that must be corrected before driving?
a.Exhaust gas including carbon monoxide can enter the cab and poison the driver
b.It always causes the engine to stall at highway speed
c.It automatically triggers the low-air-pressure warning
d.It prevents the transmission from shifting into high gear
Explanation
Leaking exhaust can allow carbon monoxide and heat into the cab and can ignite nearby fuel or wiring, which is why it must be repaired before operating. Exhaust leaks do not stall the engine on their own, have nothing to do with air-pressure warnings, and do not lock out the transmission.
