new CP[MAX_PLAYERS];

Under OnplayerConnect put

Код:

CP[playerid] = 0;

And make command to start a test

Код:

CMD:starttest(playerid, params[])
	{
	    if(IsPlayerInAnyVehicle(playerid))
		{
		    SendClientMessage(playerid, -1, "You have started driving test");
		    CP[playerid] = 1;
		    SetPlayerCheckpoint(playerid, X,Y,Z, checkpoint size);
		}
	}

And under public OnPlayerEnterCheckpoint put something like this

Код:

if(CP[playerid]==1)
	{
		if(IsPlayerInAnyVehicle(playerid))
		{
	    	DisablePlayerCheckpoint(playerid);
			CP[playerid] = 2;
			SetPlayerCheckpoint(playerid, Next X pos,Next Y pos,Next Z pos, your checkpoint size);
		}
	}
	if(CP[playerid]==2)
	{
		if(IsPlayerInAnyVehicle(playerid))
		{
	    	DisablePlayerCheckpoint(playerid);
			CP[playerid] = 3;
			SetPlayerCheckpoint(playerid, Next X pos,Next Y pos,Next Z pos, your checkpoint size);
		}
	}

And just add your coordinates and whatever you want.
