The Technical Department has recently received several complaints from fans concerning their inability to read the competition numbers of their favorite drivers. These complaints are not just directed at professional categories but also all sportsman categories. Some of the complaints have been that racer’s competition numbers are not as large as the rulebook requires, that the number fonts used are not easily legible and that the colors used are not truly contrasting (e.g. gray on black). Per the 2015 NHRA Rulebook: All contestants are required to display a permanent driver number at all NHRA Mello Yello Drag Racing Series national events, NHRA Lucas Oil Drag Racing Series divisional events, divisional NHRA Summit Racing Series Finals, and divisional National Open events. Driver numbers and class designation letters must be displayed on both side windows and the windshield. Numbers on side windows must be a minimum 6 inches high and 1 ½ inches wide. Class designation letters must be a minimum 3 inches high and 1 inch wide. Numbers and class designation on windshield must be a minimum of 3 inches high and 1 inch wide. Driver’s competition number and class designation must be displayed in a legible manner in a contrasting color to the vehicle’s background color, or light color on windows, in a prominent position, and be clearly visible to the tower personnel. Class and numbers must be in the form of permanent decals or paint. The use of shoe polish in any form is prohibited. Please make every effort you can to adhere to this rule. You all have fans and they want to be able to easily identify you.
