PKRA Club Rules

900 Definitions

The purpose of the PKRA Definitions section is to clarify ambiguous areas of the rulebook and provide guidance for the racers and track officials. These are not rules and can not be protested. All decisions made by the Race Director, Flagman or other official on these Definitions are final. 

900.1 Blocking 

Blocking is not allowed during practice, qualification or during a race. As indicated in Part 600, a member may be penalized for blocking. What is, or is not, blocking is a decision of the Starter and/or the Race Director; however, the following is intended to guide their decision and help the racer in making appropriate choices on the track. First it must be understood that the leading driver has the choice of racing line. The leading driver is under no obligation to drive the same line every lap or otherwise be predictable. The leading driver cannot be erratic in the line chosen. Weaving, turning into another driver passing you, or making abrupt changes in racing line will be considered blocking. One way to think about it is that each driver is allowed one steering change in each straightaway. For example, if the leading driver enters the main straight on the right hand edge of the track, they may move down to the center of the track, providing they maintain that line all the way to the next corner and enter the corner from the center of the straight away. Alternatively, the leading driver may enter the main straight in the middle of the track and later swing wide to enter the corner at the end of the straightaway on the best racing line. Each of these two examples depicts one steering change on one straightaway. What the leading driver cannot do is enter the straight away at the edge, then move to the middle, then move back out to the edge to make the corner. This is two steering changes and is blocking. Another example is where the leading driver may transition the straight from one side to the other for the full length of the straightaway. The leading driver may also transition at any point along the straightaway, or not at all. What the leading driver cannot do is transition part way across at the start of the straightaway then move the rest of the way over later. This would be two steering changes and is blocking. Driving down the center of the straightaway so that drivers cannot pass on either side is also considered blocking. 

Keep in mind that the primary responsibility for safety during a pass rests with the driver coming from behind. The leading driver cannot see the following driver until the kart is almost two-thirds along the leading driver. The following driver must, to some degree, anticipate the maneuvers of the leading driver and make a safe choice about how to complete the pass or back off and maintain position. Once the following driver has established position, safety is shared and the leading driver must leave racing room for the following driver to race safely or be guilty of blocking. 

Be aware, for any maneuver to be blocking, there must be someone to block. If the second driver is too far behind to make a pass then it would be legal for the lead driver to drive all over the track, without blocking, simply because there is no one to block. 

The spirit of this Guideline is that defensive driving is a part of racing. The lead driver does not have to be predictable, nor easy to pass. 

900.2 Bumping 

Bumping is defined as one kart running into the back of another kart with such force that the head of driver of the struck kart is rapidly move backwards. Bumping is NOT allowed at PKRA club events; in the interest of safety, karting at the club level should try and maintain zero contact between karts. There will always be accidental contact in close racing. Making exceptions to the non-contact rule makes it more difficult to discern bumping from rough driving. Drafting another kart, but maintaining a separation, no matter how small, is legal and can be used to great effect by skilled drivers. 

Note: Bumping another kart to push him past a slower kart (also illegal at PKRA) is not included in the definition of bumping but is covered under Rough Driving. 

900.3 Rough Driving 

Rough driving is a term commonly applied to knocking (punting, taking out) another competitor from the line or the course, nerfing, or other avoidable contact with another kart. It must be understood that there is a fine line that exists between malicious intent and inadvertent contact. The basic rule is "No Contact". Good, competitive racing sometimes sees contact between competitors. This type of contact can still be considered a violation of the rule book, depending on each incident. A driver is not to use bumping, nerfing, or pushing tactics to protect or improve their position. Officials will spot such infractions and take the prescribed action. The Race Director will employ the assistance of all race officials to identify rough driving 

900.4 Tire Warming 

Tire warming by swerving from side to side is not allowed and may incur a time penalty. This rule also applies to warm up laps for the heat(s) and the main.
