Safety Rating Methodology Beta

The rating is recomputed from the published incident log. It is never entered by hand and never stored as a separate driver field. Each eligible weekend contributes green-flag exposure and the incident points attached to steward rulings. Clean running lifts the rating gradually; incidents reduce it.

Test days are not counted. The current intake includes only official days under the Rush National Series sanctioning bodies, currently the GridLife rounds; practice and warmup sessions carry 0.25 weight, while qualifying and race sessions carry 1.00.

The same replay is used on driver profiles, the public board, and the steward tools. This page displays the live values currently used by the replay.

Each driver opens at 2.00, so the bands below that line hold drivers whose incidents have outweighed their green-flag running so far, and the bands above hold drivers who have run more clean minutes than they have given back. A driver with one weekend sits close to 2.00 either way: the rating moves slowly until there is enough running behind it to move.

Published driver profiles show a letter grade instead of the raw number. A is 3.00 and above, B runs from 2.00 to 3.00, C runs from 1.00 to 2.00, and D is anything below 1.00. The letter is advisory, like the rest of the rating. The band breakdown above still prints the exact two-decimal value for every rated driver, and stewards work from the full-precision number behind the letter.

Each involved driver receives a separate grade. The row records the worst consequence caused by the incident, not simply what happened to that driver’s own car. The column records the steward’s responsibility ruling: not at fault, shared, or at fault.

A solo off, a rule infraction, blocking or impeding, a mechanical failure, contact, a lost position, damage or a DNF, and reckless conduct are distinct rows. A mechanical failure is not treated as driver fault unless the steward assigns that row and responsibility. A rule infraction escalates to the consequence row when it caused contact or impeded safety workers. Blocking escalates the same way: when the blocking caused contact, cost a position, or caused damage, the steward grades that consequence instead. Blocking is graded at fault only, because the driver who was blocked is graded on whatever consequence followed.

Damage and reckless outcomes are not discounted by session type when the grade is shared or at fault. Serious consequences should not be cheaper because they happened during practice.

Drivers can report an incident the stewards did not catch through the report form in the Driver Toolbox. A report is logged like any other incident and graded like any other incident — with one exception. If a steward confirms that nobody had already told us about it (it was not already in the incident log, no other driver had reported it, and there was no steward or corner-worker note), the reporter’s grade on that incident is granted immunity: the incident stays on the record with its full audit trail, but its points stop charging the reporter’s rating. Immunity applies regardless of fault — a driver who caused something and told us before we knew still pays nothing for it.

The grant is a human decision, recorded with who granted it and when. Reporting alone grants nothing: a report of an incident that was already logged, already reported, or already in an official’s notes is an admission, and it is graded normally.

A granted immunity stands unless the report itself was dishonest. If the “nobody else had it” finding turns out to have been wrong, the grant is not clawed back — the steward who granted it judged the information available at the time. A steward can revoke an immunity, and a revocation must state its reason and is recorded with it in the same audit trail.

A steward can mark the incident that caused a full-course yellow. The live multiplier applies only to shared and at-fault grades. Drivers who were not at fault are not escalated for being collected in someone else’s caution-causing incident.

Exposure counts green-flag minutes. Formation, pace, out-lap, in-lap, double-yellow, and red-flag time do not count as green running.

“Driver under review” is an advisory recommendation, not an automatic suspension. The rating uses full-precision values and settled appeal state to determine its recommendation band. The sanctioning body retains final discretion over entry and sanctions.

Ratings are cumulative and do not decay. Appeals keep affected weekends provisional until the applicable review windows close.
