On Danger Canyon, you may only drive through the tunnel if there are three or more enemy players at the base, and only if the next flag you need is the center flag. [5.10]
Camping: Hijacking a hog
If you blast a hog off the cliff on Sidewinder, you may only proceed down to get the hog if all its former occupants have died. [6.13]
(a) You may not attack another player or hog if there are as many, or more, hogs in the vicinity as there are players. You must first check to see if there are other hogs in the area before attacking. This rule is to avoid "nade fests", particularly at initial spawn but also throughout the game.
(b) You may, however, attack a hog having a gunner or a passenger, if they could be an immediate threat to you getting into your own hog.
(c) You may also attack at map start if two enemies are departing in solo hogs, as they are likely to be teaming up once you are no longer a threat. [6.15]
You may only throw one grenade at a time. Your prior grenade must have exploded before throwing another one. This is true at any point, not just while you are defending yourself. Note: This rule is enforced if there is an obvious violation or a pattern of borderline violations. [7.1]
You may not jump out of a gunnerless hog to defend unless an enemy hog is firing at you. [7.2]
(a) In Blood Gulch, if a driver of a 2 or 3 person hog driving to blue base chooses to drive around to the right of the hill near 1st cliff, it must only be for defensive purposes. This means the gunner and passenger may not attack any enemies once the driver begins to drive around the hill and until the hog is completely clear of the cliff.
(b) At start of map on SideWinder, hogs must proceed direct to the first flag. Once the hogs have cleared all ice approaching first flag, they may then veer for defense. [8.4]
~ No camping or sniping on Race servers
~ Respect the admins & all players
~ No profanity
~ No team nading/rocketing
Most of the rules are pretty easy to follow, but camping can have different meanings to different people. So here is the rule about camping:
Camping is defined as sitting and waiting in a hog, on foot, etc. for the intent of killing another player. If your life isnt in danger on a Race map you should be driving. If you have to stop to shoot to save your life this isnt considered camping.
