Failed safety inspection: vehicle rejected; team eliminated from race competition (may still participate in showmanship-only); Stored propulsion / illegal propulsion mechanism: disqualification; Vehicle weight over 100 kg: DQ
Why people argue about this
People often argue that a car weighing 100 kg exactly wouldn't be disqualified, thinking it's a strict cut-off at 101 kg or more. But actually, they misunderstand the rule which states any weight over 100 kg results in disqualification, so technically, even if just slightly above, like 100.1 kg, would trigger DQ.
