Why should you never leave a petrol or diesel engine running in an enclosed space?

301. Why should you never leave a petrol or diesel engine running in an enclosed space?

The battery can become overcharged.
The tyres can lose pressure more quickly.
✓ Dangerous carbon monoxide can build up.
The engine can lose oil pressure.

Exhaust gases from petrol and diesel engines can contain carbon monoxide, a poisonous gas that can build up quickly in an enclosed or poorly ventilated space. Never leave the engine running inside a closed garage or similar area.

Why should hard braking be avoided while a motorcycle is leaning in a bend?

308. Why should hard braking be avoided while a motorcycle is leaning in a bend?

It prevents the suspension from working.
It makes the motorcycle turn more sharply.
It increases tyre pressure immediately.
✓ It can reduce stability and available tyre grip.
