BDifficulty 3/5

As general efficient-driving advice, if the vehicle and safety allow engine shutdown, beyond what duration of a prolonged stop does the DGT recommend it?

Correct answer

When it exceeds 60 seconds, if shutdown is safe.

When the stop exceeds 60 seconds, as general advice to avoid idling fuel consumption. Follow manufacturer instructions and automatic stop-start operation; do not compromise essential services or safety. This is not a universal legal rule to wait exactly one minute before always switching off: article 115 sets specific cases including tunnels and refuelling. Use lights appropriate to the circumstances, rather than always position lights merely because the engine is off.
