Tracks used for professional speedway racing are regulated by the Fédération Internationale de Motocyclisme (FIM) who provide rules concerning construction, size and safety requirements.
Speedway racing takes place on a level oval track consisting of two straights joined by two semicircles.
Tracks must be between 260 and 425 metres (853 and 1394 ft) in length, this is measured at a distance of 1 metre (3.3 ft) from the inner boundary.
Tracks may be banked, but the gradient must under no circumstances exceed 5% in the straight, 10% in the bends, and must remain constant and grow from the inner edge to the safety fence.
A white start line is marked across the track approximately mid-way along one of the straights.
The starting area is also divided into four equal parts (known as gates) by white lines marked at right angles to the start line and extending back at least 1 metre (3.3 ft).
Additional rules govern the placement of warning systems such as lights and also the construction of the starting mechanism.
The minimum track width is 10 metres (33 ft) on the straights and the bends must be at least 14 metres (46 ft) wide.
The minimum widths give each rider adequate space to safely navigate the track.
The start line and starting gate assembly is halfway along one of the two straight sections of the track.
Starting gates are simple spring-loaded mechanisms that raise two or three strands of tape to start the race.

The FIM regulations require licensed tracks to provide a garage or pit area for motorcycles as well as medical and press facilities.
Track boundaries are marked by white lines or barriers on the inside and outside the track, any rider who crosses this boundary with both wheels will be disqualified unless they only did so in the interest of safety or were forced to by another competitor.

The track surface consists of four layers of grading.
The topmost of which must be of shale, granite, brick granules or other loose material of which no individual piece can be over 7 millimetres (0.28 in) in size.
Competitors use this surface to slide their machines sideways (powersliding or broadsiding) into the bends using the rear wheel to scrub-off speed while still providing the drive to power the bike forward and around the bend.
The skill of speedway lies in the overall ability of the rider to control his motorcycle when cornering and thus avoid losing places through deceleration.
The use of asphalt, concrete and tarmac for any layer is prohibited.
The top layer must be levelled or "graded" at intervals during an event by tractors towing specially adapted rakes to evenly re-distribute the surface.
Tracks are watered before and, if needed, during meetings to prevent the surface becoming too dry and to protect the public and the riders from dust.

Safety requirements include the use of suspended wire fences, air fences and wooden fences.
Air fences are made up of inflated panels installed on the bends.
The fence is designed to dissipate energy by allowing an impacted area to compress and transfer air into the rest of the fence through blow-off valves or restriction ports connected to the other sections.
They are mandatory for tracks in the British Elite League, Polish Ekstraliga, Speedway Grand Prix and Speedway World Cup.
Neutral zones outside the track provide safe run-off areas for riders and their machinery to minimise the potential risk of injury to spectators.
The majority of tracks are dedicated to speedway or other sports such as sidecar speedway and banger racing.
For larger events, the FIM occasionally sanctions the use of stadiums that install temporary tracks such as the British Grand Prix held at the Millennium Stadium in Cardiff.
