The nature of a Head-to-Head one lap race is to be a very quick race around the circuit. Racing incidents DO and WILL happen, and they will be more prone to happen in this style of racing because both drivers are pushing their limits. Each driver is being pressured to perform their very best for an entire lap so he/she will be more apt to spin, and try to get around their competitor.
If there was a simple racing incident or even lag, just continue racing as soon as you can. If you flip over or your car is not drivable or stuck then DO NOT reset, spectate or auto-pit, until asked by an admin. Just let your car sit where it is until the end of the race.
Any intentional or avoidable incident will be dealt with at the end of the event, and penalties will effect the championship points. The end of the race is the time for discussing these events so hold your frustrations back, and continue racing the best you can as if it was real life.

There is no blocking other racers. If someone is going to pass you it is safer to let them pass than it is to try getting in their way and blocking them. Its also unfair sportsmanship, so a harsh penalty could be applied to the driver if they block another racer.
Changing your line before the other racer is too close is acceptable, but only ONCE during a straight, and you can't get back on the racing line at the end of the straight. Swinging back and forth, or pushing another driver off the corner will result in a penalty, which will be dealt with after the event.
If a driver is by your side as you are about to enter the corner on the inside, brake a little sooner to compensate because you will be responsible if you push the other driver off the track - even if its done without contact. If you don't give the space you will be considered blocking...

During the hot-lap of your qualifying session, and during any of the races of any of your matches you are expected to drive the track to the best of your ability with the car of choice. More than two tires on grass at anytime is considered cutting.
Any situations that arise will be reviewed after the event and penalties will be applied where needed. In some situations non-cutting layouts will be used, and cones will be placed to designate cutting. Penalties will only be given to the racers that gain an advantage by going off the track, if the situation was unsafe and it was needed to cut then the should slow down and lose anytime or position they may have gained.
If a racer follows that guideline no penalty should be given.

If a racer disconnects they may reconnect to the server and still take part in the event. However if they become disconnected in the middle of their race it is considered a loss and they are knocked out of the competition. In the event that a racer is disconnected they must connect before their match begins or they are automatically eliminated.
If you step away from your computer and are away during the time your match is starting, you will have 60 seconds to hop in the car and get on the track. If you do not get on the track in the alloted amount of time, you will be disqualified. This includes joining even 1 second too late. 60 seconds is more than enough time for a racer to join the race, and the goal of this limit is to keep the event moving.
