Recently NHRA released new safety standards for late-model vehicles, which has caused some confusion on what modifications are acceptable and those that disqualify exemptions. The 9.00 ET and 150 mph limits for 2014-and-newer vehicles are allowed due to the OEM safety gear. Any vehicle modifications that impede on the function of those factory-supplied safety devices immediately change the classification back to the 10.00 and/or 135 mph limits. This includes the addition of a roll bar or roll cage because side bars and other components could infringe on the door/curtain airbag deployment.

All specific safety rules and requirements are listed in the NHRA rulebook and that serves as the ultimate guide.
 
All events under the sanctioning bodies NMRA Ford Nationals and NMCA Muscle Car Nationals utilize NHRA safety standards, including the new 9.00/150 mph limits. These directly effect several of the street car and index categories and will allow an increase in participation.
