1.3 Stop Lamps

Information Method of Inspection Reason for rejection
This inspection applies to: all machines, except those which have neither front nor rear position lamps, or has such lamps permanently
disconnected, painted over or masked that are

• only used during daylight hours, and
• not used at times of seriously reduced visibility

If this situation occurs the machine presenter should be issued with a VT32 (advisory notice) recording the above.

If a stop lamp is fitted, it must meet the requirements of this inspection, but need not be fitted to a machine which:

a. cannot exceed 25mph, or
b. was first used before 1 January 1936, or
c. was first used before 1 April 1986 and which
has an engine capacity of less than 50cc.

Machines first used before 1 April 1986 must have a stop lamp that operates from at least one brake control.

Machines first used on or after 1 April 1986 must have a stop lamp that operates from both brake controls.

However, a small number of machines first used from this date were approved with the stop lamp operated by only one control. A machine should only be failed if you are certain that it was originally manufactured to operate from both controls.

On machines without a battery or with an insufficiently charged battery, it will be necessary to run the engine.
