Safety and your vehicle
Your exhaust suddenly becomes very loud. What does this most likely mean?
- There is a fault, such as a hole in the exhaust, that should be repairedCorrect
- The engine is running perfectly and needs nothing
- The car will use less fuel from now on
- You should drive faster to quieten it down
Why?
A sudden loud noise usually means a blown or holed exhaust, which can be noisy, illegal and let fumes into the car. Annex 6 of The Highway Code says the exhaust system must be working, so have it repaired promptly.
