ASN Canada FIA’s 2005 karting
regulations made neck collars optional as opposed to mandatory. Since the
publication of the regulations, there has been much comment on the neck collar
issue, mostly centered on why we made the change.
ASN made this change because we
could not find clinical evidence to support the common notion that the wearing
of a neck collar prevents injuries to the neck or serves to help avoid injury to
the collar bone.
Prior to making this change ASN
consulted with a member of the FIA Institute for Motor Sport Safety and of the
International Council of Motorsport Sciences.
ASN has observed helmets coming
off during track incidents on several occasions, possibly as a result of
compromised helmet fitting and chin strap tightness due to the wearing of a neck
collar.
-
The CIK-FIA does not require the wearing of neck collars.
-
There are no CIK approved or homologated neck collars.
-
Collars are not commonly used in Europe.
- British and Australian
karting rules do not require the use of a neck collar.
ASN encourages all drivers to
ensure that helmets are fitted correctly according to manufacturers’
recommendations.
We ask that you review helmet
fitting guidelines “Get Helmet Smart” and the Bell Helmet Fitting Guide for

Measurement
Proper
helmet fit is a vital component to the performance of a helmet during an impact.
In order for the helmet to perform properly during an impact, it must stay
securely on the head.
Measuring the head is a starting point for the entire sizing procedure. Due to
varying shapes, heads that are apparently the same size when measured by a tape
may not necessarily fit the same size helmet.
A small metal tape measure, or a cloth tape may be used to make your initial
measurement. Alternatively, a string can be used which can then be laid against
a measuring tape.
The circumference of the head should be measured at a point approximately one
inch above the eyebrows in front, and at a point in the back of the head that
results in the largest possible measurement. Take several measurements, to make
sure you have the largest one.

Measure around the head, just
above the eyebrows and around the back, getting the largest measurement possible. |
Correct helmet fit is critical. A helmet should be as
snug as possible without giving you a headache.
You can start with your hat size but that is just the beginning. With the helmet
on, chin strap undone and neck held rigid, twist the helmet left and right to
check for excessive play.
Then, with the chin strap on, rock the helmet back then forward to see if it can
roll off.
Finally, watch a half-hour TV show with the helmet on. If it feels snug during
these tests but doesn’t give you a headache, you have the right size.
