Section 4 - Vehicle Regulations
4-1	The vehicle must be driven into and out of the judging lanes. Additional Guidelines: The vehicle's motor must be used to propel the vehicle into and out of the judging lanes. (Starter motors, etc. may not be used as a means of propulsion.) Exception: Some events may prohibit the operation of motor vehicles. In situations such as this, or when safety is an issue, compliance with this rule is waived.
4-2	The size and location of the vehicle's doors must not be altered. Additional Guidelines: Extreme competitors may install "bolt tabs" or a "bolt strip" (for securing the doors) along the perimeter of the door openings provided the maximum width of each tab or strip is less than 2 inches (5.08 cm). If a bolt tab or bolt strip is attached to the B-Pillar, it must be easily removable to permit compliance with the "string test". As a minimum, the vehicle must have a door for the driver and another for the passenger. Each of these doors must be located in the traditional locations for the driver and passenger. (i.e. Opposite sides of the vehicle.) Exception: Vehicles that were originally manufactured with only one door. (i.e. Mail delivery jeep.) Adhesive foam tape may be used in lieu of the factory door seal. (You may use one or the other but not both.) The maximum thickness of the tape is limited to 0.5 inches (1.27 cm). This limitation does not apply to Extreme Division competitors.
4-3	This rule (4-3) applies to Extreme Division competitors only. The OEM glass in the windshield and / or side windows of the vehicle may be replaced with another material as long as that material approximates the location and functionality of the original equipment. (i.e. Plexiglas, bullet-proof glass, or another fully transparent material.) Additional Guidelines: The "slant" of the replacing material must approximate that of the OEM glass. The maximum total thickness for any replacement material is 4 inches (10.16 cm). A uniform material thickness must be used for all windshield panels. (Each panel in the windshield must be of the same material and thickness.) A uniform material thickness must be used within each side window panel. (Each panel in a side window must be of the same material and thickness.) Consistency must only be maintained within a given window. The relationship between the dash and the windshield shall be such that the sensor can be placed on the windshield and the proper distances from the sensor to the dash (4 inches or 10.16 cm) and the sensor to the windshield pillar (12 inches or 30.48 cm) can be achieved. The unobstructed viewing area for the front windshield must be 4 square feet (0.3716m^2) or larger. The unobstructed viewing area must be symmetrical in nature, with equivalent transparent areas on both the driver and passenger sides of the vehicle. Important: Only areas of the windshield that are not impeded in any way will be considered unobstructed. This includes window tint. There is no limit to the number of external windshield braces that may be used as long as their existence does not violate other applicable rules. A secondary windshield and / or windows may be used in conjunction with the OEM glass as long as the maximum distance separating the two materials does not exceed ¼ inch (6.35 mm) at the center of the windshield and / or window. The unobstructed viewing area for the driver and passenger side windows must be 200 square inches (1290cm^2) or larger (per window). Side windows do not need to be operational. (They don't need to roll up or down.) Competitors who have replaced the passenger side windows with Plexiglas or another similar material must provide a 1-inch (2.54 cm) diameter hole (with stopper) through a transparent area of the material for the measurement sensor cable.
4-4	Modifications to the external OEM "skin" (body) of the vehicle are not permitted if the modification in question will result in a change in the vehicle's interior volume. The dBDRA defines the "skin" of the vehicle as the external shell (top, front, back, and sides) of the vehicle's OEM body that gives the vehicle its distinctive appearance. This is also the part of the vehicle that is normally painted. The underside or undercarriage of the vehicle is not considered to be a part of the OEM "skin". Additional Guidelines: "Chop-tops" are prohibited. Non-OEM extended roofs are prohibited. Non-OEM vehicle extensions or "stretches" are prohibited. Cut-throughs in pickup trucks are permitted in the Street Max, Super Street, and Extreme Divisions provided the enclosure and / or other equipment that is located in the bed of the truck does not extend above the sidewalls of the bed. If the pickup has a commercially available camper shell, then the sidewall restriction does not apply. Homemade camper shells are strictly prohibited. Modifications that are strictly cosmetic in nature, or that do not affect the internal volume of the vehicle are permissible. This includes spoilers, hood scoops, air dams, fender flares, etc. Crushing in the roof or the doors of the vehicle in such a manner as to alter the vehicle's interior volume is prohibited. External bracing on the skin of the vehicle is prohibited.
4-5	The officiating staff must be afforded a clear view inside of the vehicle when looking through the windshield and side windows of the vehicle. Window tint, stickers, or other materials which could occlude the judge's view may not be placed on the windshield within a 6 inch (15.24 cm) radius of the sensor placement location.
