CONCORD, N.C. -- Repairing damaged vehicles during a NASCAR race sometimes is as common a sight as pit stops, restarts and checkered flags.
But the extent to which teams can make repairs will be more tightly policed beginning with the 2017 season.
NASCAR officials unveiled a new Damaged Vehicle Policy on Wednesday at the sanctioning body's Research & Development Center, a policy that will be enforced in all three national series -- Monster Energy NASCAR Cup Series, XFINITY Series and Camping World Truck Series.
Under the guidelines, teams no longer will be allowed to replace damaged body parts that are the result of accidents or contact. Repairs, such as fixing damaged sheet metal, will be allowed; however, teams will be given five minutes to fix damage once they enter pit road. If the damage requires the car to go behind pit wall or to the garage for repairs, the car will not be allowed to return to the race. Also, if the repairs take longer than the five minutes allowed, the car will not be permitted to return to the race.
Once repairs have been made, a car is still required to maintain the minimum speed determined for that event. Once that has been accomplished, the five-minute clock is reset in case the car needs to come back down pit road.
Previously, teams were allowed to replace any damaged panels or parts with no time limit and no penalty. Quarter panels, splitters, hoods and deck lids damaged in accidents were often removed and replaced. Some repairs were completed on pit road; more extensive damage often meant a trip to the garage. Each time, the driver was sent back out onto the track as quickly as possible.
That will no longer be the case.
"We have a lot of cars that are going back on the track that end up in 38th position, for instance, that probably don't need to be out there from a safety and competition aspect," Scott Miller, NASCAR senior vice president of competition, told NASCAR.com, "because they always tend to bring out more yellows with stuff falling off."
Heavily damaged cars that need extensive repairs that can't be done on pit road, Miller said, "are essentially going to be out of the race.
"There will be many circumstances and many things happen and you will continue to see it where cars are in wrecks and never go to the garage area. They come down pit road, they work on things … and they go back out and make minimum speed. They continue to work on the car as the race goes on. That will still completely be in play."
Miller said the move is to help officials, who didn't often see what goes on in the garage but can better observe repairs on pit road.
Miller has worked "on the other side of the fence" as a crew chief and is aware of the hurried atmosphere surrounding a car undergoing significant repairs in the garage.
"I've been involved in crash repairs and that's not a great situation down there in the garage with 20 people running around, oil leaking on the floor, things catching on fire and sharp sheet metal being cut off," he said. "It's a fairly unsafe situation. And at times it would be unsafe really for the driver to get back in a car that was damaged that heavily. There's nothing that doesn't come with some downside, but I think there is a lot of upside to where we are going with this."
Safety is a crucial component of the policy, and for any vehicle undergoing repairs, the integrity of the safety systems "must be maintained."
Teams will be allowed to correct mechanical or electrical failures that aren't the result of an accident or contact without penalty. Such repairs may be done on pit road or in the garage area, and the five-minute clock will not be in play in those instances.
"We're not going to tell a guy who breaks his transmission at Watkins Glen or Pocono, for instance, and coasts into the garage area that he's out," Miller said. "Because that doesn't create an unsafe situation; that is a mechanical failure.
"It's more about crashed vehicles and all that is involved with that, from the crew guys to the drivers to dropping more debris on the track, which always happens. … So there are exceptions for mechanical failures, those things can be rectified in the garage. That's going to be up to the series director's discretion to make those calls, but it's not going to be that difficult."
There will be modifications to at least two pit-road penalties under the policy for those making repairs. Any driver receiving a pit-road speeding penalty (entry or exit) will lose 15 seconds from the five-minute clock. Any team sending too many men over the wall will result in that car being removed from the race.
"Speeding comes with an additional penalty because speeding in or out is a way to circumvent the clock," Miller said.
When a car is damaged and repairs are made on pit road, teams know they will be at the tail end of the longest line, so extra men often go over the wall. (Each team is allowed six to work on the car and one to service the driver and/or windshield.)
"That's another thing we discussed with the teams and internally," he said. "Too many men over the wall is also defeating the purpose of the policy; it would encourage teams to bring extra people well-versed in going over the wall to repair cars. So too many men over the wall just has to signal the end of that car's day."
What will race fans see with the new policy? It's what they won't see, Miller said, that is behind the change.
"What they won't see is stuff we don't like to see, cars running around out there with stuff flying off," he said. "We don't like that because it creates yellows, it creates debris for other cars to run over, it creates a dangerous situation. That's what they won't see. What they will see are quality cars on the race track racing one another."
The 2017 NASCAR season gets underway Feb. 24-26 with all three national series competing at Daytona International Speedway. The Daytona 500, the season's first Monster Energy NASCAR Cup Series points race of the year, is scheduled for Sunday, Feb. 26 (2 p.m. ET, FOX, MRN, SiriusXM NASCAR Radio).
