What 'three step' rule; can you cite a place in the rule book? In general, any step on or inside the lane line is an infraction, it does not take three consecutive steps, (although it is easier to see when there are three in a row, that is not central to the rule).From IAAF :Running in Lanes3. (a) In all races run in lanes, each athlete shall keep within hisallocated lane from start to finish. This shall also apply to anyportion of a race run in lanes. (b) In all races (or any part of races) not run in lanes, an athleterunning on a bend, on the outer half of the track as per Rule162.10, or on the diversion from the track for the steeplechasewater jump, shall not run on or inside the kerb or line markingthe applicable border (the inside of the track, the outer half ofthe track, or the diversion from the track for the steeplechasewater jump).Except as stated in Rule 163.4, if the Referee is satisfied, on the reportof a Judge or Umpire or otherwise, that an athlete has violated thisRule, he shall be disqualified.4. An athlete shall not be disqualified if he(a) is pushed or forced by another person to run outside his lane oron or inside the kerb or line marking the applicable border, or(b) runs outside his lane in the straight or outside the outer line of hislane on the bend,with no material advantage thereby being gained and no other athletebeing obstructed.5. In competitions held under Rules 1.1(a), (b), (c) and (f), the 800mevent shall be run in lanes as far as the nearer edge of the breaklinemarked after the first bend where athletes may leave their respectivelanes.The breakline shall be an arced line, 5cm wide, across all lanes otherthan lane 1. To assist athletes identify the breakline, small cones orprisms, 5cmx5cm and no more than 15cm high, preferably ofdifferent colour from the breakline and the lane lines, shall be placedPage 141 RULE 163The poster earlier essentially outlined the situation adequately. In general, on straights, the only issue is interfering with other runners while the race is being run (i.e., after the finish, as with Powell (?) several years back, this does not affect the results). On the curve, tripping and going over the rail will not generally result in a DQ because there is no advantage gained (in fact, it usually is a disadvantage).

I'm pretty sure the USATF rules follow the IAAF rules, and from my earlier running days I was always told that any three steps in a row (as observed by an official) would result in a DQ. Interpret this as you will, but I assume both of the following would result in a DQ:
-three consecutive steps (left foot, right foot, left foot)
-three consecutive steps with the same foot (left foot out, next left foot out, next left foot out)
