Road Rule 126.

Keeping a safe (stopping) distance behind vehicles

A bicycle is a vehicle.

I argue it is negligent for a cycling bunch to be a No Stopping Zone.

A cyclist who is concentrating will have a Brake Reaction Time of about 2½ seconds to apply his/her brake levers in an emergency situation.  By using the Bicycle Brake Stop Calculator,

if the cyclist is travelling at 40 km p/h which equates to 11.11 metres p/s,

the Bicycle Brake Response Distance would be 27.78m.

(That means a cyclist riding at 40kmh has travelled nearly 28 metres before the brakes have been applied PeteDowe)

Bicycle Brake Reaction Time of 2½ seconds, which has been used in “Guide for the development of bicycle facilities” by the 'American Association of state highway and transportation officials', is the mode Bicycle Brake Reaction Time used in most bicycle modelling.









Bicycle Brake Reaction Time means the time a cyclist needs to -


• see a danger ahead;
• perceive what it means;
• decide on a response; and
• instigate that response,

when the bicycle continues to travel at is velocity.





Bicycle Brake Reaction Distance means the distance a bicycle travels, prior to applying the brakes, whilst a cyclist -

• sees a danger ahead;
• perceives what it means;
• decides on a response; and
• instigates that response by applying the brakes.

A cyclist who is concentrating will have a Bicycle Brake Reaction Time of about 2½ seconds to react

to 'instigate a response' by squeezing his/her brake levers according to different, 

previously determined, pressure levels for the front and rear brakes when in an emergency situation.

“Most rules in the Road Rules apply to bicycle riders in the same way

as they apply to drivers—

There are some other rules that are for bicycle riders only,

or that have exceptions for bicycle riders.”


Road Rules Victoria 1999

Victorian Government Gazette




A Bicycle is a vehicle.




Road Rule 126. Keeping a safe distance behind vehicles


A driver must drive a sufficient distance behind a vehicle 

travelling in front of the driver so the driver can, 



if necessary, stop safely to avoid a collision with 

the vehicle.

“The evidence establishes that there can be difficulties,

especially for inexperienced cyclists, in stopping safely 

when traffic lights are red, when they are riding in bunches.”
