JOLIET, Ill. -- Aric Almirola said the ambulance that took him to the care center after he broke his back in a crash at Kansas got lost in the infield

Matt Kenseth and Kevin Harvick were among the drivers who raised concerns this week about lax safety issues in the wake of a wayward ambulance that got stuck on pit road at Richmond.

Almirola said he also had an issue with his emergency vehicle.

"The ambulance driver and guy in the passenger seat were yelling. They were stuck somewhere in the infield amongst the motorhomes and couldn't figure out how to get back the infield care center," Almirola said. "I have met with NASCAR on it and they are trying to figure out ways to rectify it. They run all their pre-race routes on Thursday or Friday and then through the weekend a lot of campers show up and the infield looks drastically different on race day than when they run their pre-routes. I think that was one of the challenges they had in Kansas. I did get lost in the back of the ambulance and that wasn't very much fun in the moment."

NASCAR said it will continue to "work with the tracks and safety teams to improve in every aspect of support. Safety is paramount, and it's something we work hard at all year long."
