1994 Northern Territory Cannonball Run speed sign

Forty kilometres outside of the Darwin city limits has always been known for driving “flat out.” There is literally no posted speed limit.

Before the 1994 Cannonball Run began, the competitors were told the rules were “go as fast as you like.”  After the death of the two Japanese dentists driving the Ferrari F40, there was a limit of 180 kilometres per hour placed on all competitors.  Essentially, the race winner was decided at this point.  With the exception of a car having a catastrophic break down in front of you, the position you were in at the time of the accident was the position you were going to finish in.  Overtaking was not permitted. Everyone had to travel at up to 180 kph.
