What are the dangers of travelling in a vehicle that has a leak from the engine's exhaust system?
Pick an answer to test yourself
The correct answer: Penetration of burnt gases into the passenger compartment, causing dulling of the senses.
A leak from the engine's exhaust system is dangerous because burnt gases can penetrate the passenger compartment and dull the senses of the driver and passengers. It is wrong to think that there is no danger in travelling like this.
