An ambulance is on emergency duty using only its special lights. Does it have priority if omitting the audible emergency signal creates no danger to other road users?

Correct answer

Yes, provided that omitting the acoustic signal poses no danger whatsoever to other road users.

Yes. Under these conditions it must use its special lights alone and retains priority status. The general rule is to use special lights and the audible emergency signal together, but this exception applies. That signal is not an ordinary horn. Being on an urban road alone does not confer priority, and an ambulance does not automatically have priority when it is not on emergency duty. Other users must facilitate safe passage as circumstances require.
