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."   
Also

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

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

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.





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.

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








“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.

Bicycle Brake Response Distance



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 the cyclist has travelled nearly 28 metres before the brakes have been applied PD)



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.

The following is the Federal Requirement for bicycle stopping distance with a hand brake.  It is in 16 CFR 1512.5.  Hope it helps.

(1) Stopping distance. A bicycle
equipped with only handbrakes shall be
tested for stopping distance by a rider
of at least 68.1 kg (150 lb) weight in accordance
with the performance test,
§ 1512.18(d)(2) (v) and (vi), and shall have
stopping distance of no greater than
4.57 m (15 ft) from the actual test speed
as determined by the equivalent
ground speed specified in
§ 1512.18(d)(2)(vi).

On a two wheeled vehicle, you cannot jam the brakes on for a 'full' in an emergency stop.
You have to achieve weight transfer first. This means an initial gentle application of the brake before a big squeeze. If you jam them on instantaneously without moving the body weigh backwards, ideally over the seat, the front end can go out from under you, particularly if you have powerful brakes like hydros.



Also on a bike, when braking heavily you'll find that you subconsciously lift off the brakes momentarily as you cross bumps etc on the road surface (eg cracks, manhole covers etc). This is to stop the wheel locking as it is unweighted over the bumps. In a car this isn't necessary.
