old ambulance people killed

[DRGIGGLES]

I havent seen this movie for year and years now.  the most i can remeber is that there is an old style ambulance (like the ghost buster car) that is taking people that were killed for some reason at the end a man is going to be ramed by the ambulance and he dodges it and the ambulance flies of a cliff tyle area and blowes up.  does anyone know what movie i speak of?

1990 - Larry Cohen's "The Ambulance"

I only vaguely remember it due to James Earl Jones' involvement.
