Home > Rally principles and definitions


 

A rally involves driving a vehicle between a series of control points against the clock. Each vehicle traverses the course independently, and no direct head-to-head racing takes place. The team or driver with the fastest time over the correct course is the winner.

In order that the rally may be conducted smoothly, a number of standard principles have emerged that everyone expecting to take part should know. Each rally will be subject to a set of regulations "the regs" which are published beforehand and given to every competitor. Usually the regs will follow the standard regulations laid down by the motorsports governing body for your country, and these have the force of law. In the UK, the governing body is the Royal Automobile Club Motor Sports Association (RACMSA), and the regulations are published annually in the " blue book ". Each rally must adhere to these regulations, though some rules permit some variation. In any case, you should familiarise ypurself with the blue book for the sport you wish to take part in, and read the regs before the actual event.

While stage rallies are usually daylight events, (with night stages an occasional feature), all road rallies are night events. This is for safety and practicality - since they run on the public road it would be nice if they were deserted. In addition, most road rallies take place in remote areas to avoid a nuisance to the public.

1 Controls

Controls may be manned or unmanned. If manned, an attendant called a Marshal will perform the appropriate duties for the type of control. You are expected to stop at any manned control along the route unless instructed otherwise. Marshals are usually volunteers and volunteering for this duty on your local club event is a great way to get involved.

2 Sections and stages

A rally is usually divided into a number stages or sections. These are classified as competitive sections or special stages, and non-competitive or link sections. The terminology used depends on whether the rally is a special stage rally or a road rally, but they mean the same thing in principle. You are only timed against the clock on a competitive section. On a non-competitive section, not only are you not timed, but you will be penalised for EARLY arrival - the penalty may be disqualification. This is because link sections are used to take the rally through built-up areas, noise-sensitive areas, and other parts of the route where it would be unsafe or unwise to drive in a competitive manner.

Each section will have a start control and a finish control, perhaps with other intermediate controls. In addition, the rally as a whole will have a main control at the start and at the finish (which may be in the same place), and other main controls if the rally is broken up into separate halves,which is common on longer events.

A typical road rally might use the following nomenclature for controls:

The route information which is supplied to you before the event will clearly show which order you are expected to visit the controls. Note that you are also penalised for visiting the controls in the wrong order - accuracy is as important as speed on a rally.

3 Unmanned controls

Some rallies will make use of unmanned controls, frequently known as " codeboard s". These are used to confirm that the competitor took the correct route when there are insufficient volunteers available to set up a manned control. They are very common on club events. A codeboard is a small sign placed at the side of the road on which is written some sort of alphanumeric code - often just a single letter, though longer sequences are sometimes used. By writing down the letter as you pass it, the adjudicator can check whether you took the correct route.

4 Timing

Time is a key element of rallying. Every section on the event will have a " due time". This is the time the organisers have allowed for a competitor to travel between those two controls by the correct route. There are severe penalties (including disqualification) for being EARLY - this is for safety - so simply driving as fast as possible from control to control is not a good technique. On a non-competitive section, times are generous, and are usually calculated based on an average speed of 30mph or less. It is OK to be late on a non-comp section (though see below about maximum lateness), but never early. Non-comp sections are timed to the nearest previous whole minute.

On a competitive section, there is also a calculated amount of time to complete the section, known as the "bogey time". This is normally unattainable! Here, the object is clearly to drive as fast as possible and set the lowest possible time. However, rules vary for different forms of event. UK road rally rules currently prohibit the use of bogey times on the public road - perhaps for obvious reasons. A road-rally competitive section is timed such that in theory no speed limits need to be broken to "beat the bogey". In practice this would lead to a dull event with little to choose between teams, so organisers often make these sections extremely challenging in terms of both driving and navigation such that the bogey time is unattainable in practice. Competitive sections are timed to the second.

While there are no penalties for lateness at the end of a link section, the organisers will impose a maximum permitted cumulative lateness - usually 30 minutes. Exceeding this lateness (know as going Over Time Limit, or OTL) will usually result in disqualification. This rule is there to allow the rally to be run efficiently, and let the various volunteers get home at some point! Some events allow lateness to be made up in certain places to help you avoid OTL, most road rallies and club events do not, by law.

Managing the time is a key responsibility of the navigator. They must ensure that the driver is always in the right place at the right time - that is the definition of navigation in this context. In order to provide a seaparation between competitors on the road, teams are started at fixed intervals, usually one minute. The competition number that you are allocated for the event is also (handily) the number of minutes after the start of the event that you are due to leave. As the vent progresses, you must calculate your due time at the next control, allowing for any accumulated lateness. For non-competitive sections, the due time to complete the section is always clearly stated in the route information. As all marshals on the event that deal with the time (most) have a set of highly accurate synchronised clocks, so should the navigator synchronise her own clock at the start of the event to ensure there is no confusion.

The once standard method of timing - targa timing is now banned for road events, though may be seen on other kinds of events.
