Solo Trials events are entry level events and provide a speed rush
without the possible dangers of the following venues. These events can be run
without a driver's suit and/or rollbar (unless you have a convertible).
A Hill Climb, as the name implies, sends one automobile up the hill at
a time in pursuit of the fastest time of the day or in its class.
Time Trials are defined as "speed competition on a closed course with
one car at a time running against the clock for the fastest time." Roll bars,
helmets and seat belt/shoulder harness combinations are required in Solo I just
as they are in racing. Either a set of underwear or outer driver's suit of
SCCA-approved flameproof material must be worn and the combination of both the
suit and underwear, which is required in racing, is recommended for Solo I.
