When must you pull over and allow an ambulance or fire engine to pass?undefined
If it is travelling faster than you want to
You don't need to let it past - you can speed up so you're not holding it up
If its siren and/or red flashing lights are on
At all times

If an ambulance or fire truck is not using its lights or sirens, it means they do not have an emergency to respond to and are considered regular vehicles; you do not need to give way to them. However, if the siren is sounding, you must give way.
