Race within the rules
This page explains what governing bodies, regulators, standards bodies and researchers publish. It is not a substitute for your class's rule book, a track's safety rules, the race director or the makers' instructions.
This section is a reference, not a safety course. It does not replace a class's rule book, a track's safety rules, the race director or the makers' instructions. Anyone hurt by a car, a battery or fuel needs medical care, including anyone who swallows fuel or gets it in the eyes; a serious injury is a matter for the emergency services; and a burning or smoking battery is a matter for the fire service.
How these pages are written
- Rules are never merged. Every racing rule names its body, document, edition and section. IFMAR, EFRA, ROAR and the BRCA each bind only their own events, and a page covering several keeps each in its own section or table column. Racing rules are not law.
- Gaps in the rule books are admitted. EFRA's 2026 General Rules, IFMAR's General Rules for World Championships, ROAR's current rule book and the BRCA's handbooks could not be read for the research. Where one of them would matter, the page says so, and ROAR's rules appear only through a 2024 ROAR list of rule revisions and older or second-hand sources, the latter labelled as unconfirmed.
- Every injury figure keeps its source. Numbers are given with their publisher, data system, years and population, and are never added, averaged or turned into trends. The US surveillance category used covers every non-riding toy vehicle, not RC cars alone, and no study of injuries in RC car racing was found.
- Fuel hazards come from public agencies only. What these pages say about methanol and nitromethane comes from NIOSH and Great Britain's Health and Safety Executive, with one fire-service point labelled as resting on a single report.
- The CPSC's 2008 battery alert is about aircraft. The US Consumer Product Safety Commission's 2008 alert concerns RC helicopters and airplanes, not cars, and the pages say so wherever it appears.
- Gear is not presented as prevention. No page says a LiPo sack, hard case, barrier or any other item prevents fire or injury. Where these appear, it is because a body's rule requires them, and the page reports the rule.
- Nothing is taught or treated. These pages contain no driving technique, building, setup, tuning, charging, storage, disposal or fuel-handling procedures, no first aid and no firefighting.
- No money, no names. Insurance appears by who requires it, with no amounts, and the safeguarding page names policies, not people. Where something was looked for and not found, the page says not found, which is not the same as not existing.
The pages in this section
- Battery fire risk: what the CPSC, OSHA, a UL fact sheet, US transport regulators and two UK fire services say about lithium battery fires, and why no RC-car fire count was found.
- Fuel hazards: methanol and nitromethane kept apart, from NIOSH and the HSE, including the optic-nerve hazard, a flash-point disagreement inside NIOSH and the HSE's March 2026 report.
- Injury data: CPSC estimates for all non-riding toy vehicles, case reports of swallowed model-engine fuel, a burns study with no RC cases, and the gaps.
- Track and rostrum rules: EFRA's barriers, rostrum, marshal and first-aid rules, IFMAR's rule 3.8, what is known of ROAR's and the BRCA's, and the first-aid disagreement.
- Battery rules at events: hard cases, voltage caps and LiPo-sack rules as EFRA, IFMAR and ROAR write them, and where they differ.
- Noise and mufflers: EFRA's registered mufflers and noise trap, IFMAR's 85 dB limits, and the noise law that was not found.
- Youth and junior rules: each body's age line for juniors, marshalling ages, and why no minimum racing age was found.
- Insurance: compulsory event insurance under EFRA and IFMAR, and the cover the BRCA and ROAR attach to membership.
- Safeguarding: the BRCA's 2024 policy as its published summary describes it, and the bodies for which no policy was found.
