Cycling Safety Cycling Safely Beach Road Bunch Cycling Bicycle Brake Reaction Time 2.5 Seconds Muggaccinos Road Rule 126 Stopping Safely Negligence Community Safety No Stopping Zones

This Blog strongly opposes 
certain reforms 

VicRoads is currently considering:

"under one suggested reform, 

cyclists could be allowed to treat red lights as Give Way signs. 

And the same could also APPLY at pedestrian lights."   


"PERMITTING cyclists, riding cautiously, to proceed past a stationary tram;"

"ALLOWING all riders to use the footpath, provided that they give way to pedestrians."

There are “No formal training programs to develop bunch riding skills...”

  • Supervision is the key. Don’t let your child near the road unsupervised until you are sure they can stop safely and cross roads safely.

Bicycle Victoria's Report into Cycle Deaths in Victoria (2002)

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.
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.

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 Brake Reaction Time of about 2½ seconds to apply his/her brake levers in an emergency situation.  By using the Bicycle Brake Stop Calculatorif 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.

A Brake Reaction Time of 2½ seconds, which has been used in the below separate formulae for km/p/h and m/p/h on page 41 of  

'American Association of state highway and transportation officials' is the mode Bicycle Brake Reaction Time used in most modelling.

Road Rule 126.

Keeping a safe distance behind vehicles

A bicycle is a vehicle.

The CycleSport Victoria and Amy Gillett Foundation submission to Coroner Johnstone’s inquest into the death of Pedestrian James Gould stated:

“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.”

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

as it affects the safety of all road users.

Bunch cyclists have a duty of care to each other, and to other road users 

to keep a safe stopping distance behind the bicycle vehicle in front

and to form cycle bunches which can stop safely.

Pete Dowe
Road Safety Advocate

“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

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.
