Competition numbers will be assigned as the membership number of the vehicle owner and/or driver. Numbers assigned to another member may be used by negotiation with the membership number holder concerned. In case of dispute, the number reverts to the membership number.
Numbers shall be a minimum of 3in. high. The current class designation shall appear on the race vehicle adjacent to the number. The sale of a race vehicle does not transfer the number to the new owner.
Changes shall be reported to the Competition/Entry Numbers Coordinator
As from Speed Week 2017 your Entry Number (which in most instances is also your member number) is the only number to be displayed on your vehicle.
You will also need to display your class details, so that other entrants and spectators are aware of what class you are running in. The driver/rider name is optional and not required by officials.
Multiple riders / drivers
If there are multiple drivers/riders, each one will have their own entry number and this is what needs to be displayed when they are in control of the vehicle. No other entry numbers are to be visible at that time.
If a vehicle is entered in multiple classes, by default the first class will use the driver/riders member number. For each subsequent class (and entry) a unique entry number will be generated by registration when they receive your entry and you will be notified of this number as soon as possible after your entry is received.
Then at Speed Week when you change class, the unique generated number (and class details) are what needs to be displayed on the vehicle when it presents at the start line.
Note: This unique generated entry number is only used for that event.
Use of another number
If an entrant has permission to use another number other than their member number, this will now become their entry number.
How it's done
Many cars with multiple drivers now have a slide in card holder in the rear side window, it is an easy job to just swap the card as the driver changes. With the bikes we suggest fitting a panel with your entry number and class details that can be easily unbolted and swapped over. For those that want to sign write their vehicle that’s fine, but you will need to obscure entry details that are not being used.
These changes have been introduced to make it less confusing for the starters and start line volunteers and to provide consistency of the information given to the timers.
Here are two great examples of how we want it done.
