Does knocking down a hurdle automatically disqualify a runner?
No. A hurdle falling by itself does not automatically disqualify a runner. TR22.6 separately lists a foot or leg beside a hurdle and below its top plane during clearance, knocking down or displacing a hurdle by hand, body or the front side of the lead lower limb, and a knockdown or displacement that affects or obstructs another athlete or also breaks another rule. TR22.7 says a knockdown alone does not cause disqualification or prevent a record, subject to the listed exceptions. The referee considers the specific conduct and its effect; a fall in a clip is not enough to decide a real incident.
For Track fans, athletes, and new officials trying to understand the hurdle-knockdown rule. · Updated
A fall alone is not the rule test
The current text does not require officials to find that a runner deliberately knocked down a hurdle. Its Comments say that “knocking down” a hurdle is not itself a disqualification and explain that objective factors in TR22.6 replace the older reference to deliberate action. The way the hurdle was contacted and what happened to other runners still matter.
Check the separate conditions in TR22.6
The rule lists several distinct grounds. Keep them separate when explaining what happened: a hurdle can be knocked down, displaced, or cleared in a way that infringes another rule.
- During clearance, a foot or leg beside the hurdle and below the horizontal plane of its top bar is a listed disqualification condition. The Comments say this applies to both lead and trail legs.
- Knocking down or displacing a hurdle by hand, body or the front side of the lead lower limb is listed. The Comments give a hand and a runner’s chest while running through the hurdle as examples.
- A direct or indirect knockdown that affects or obstructs another athlete, or accompanies another rule infringement, is listed.
- A direct or indirect displacement with significant effect or obstruction, or another rule infringement, is also listed.
Consider the effect on another lane
The Comments say that a hurdle in another lane that has already been cleared, or a displacement that does not significantly affect another athlete’s progress, does not necessarily mean disqualification by itself. Officials still have to consider other infringements, such as an athlete leaving their lane or a foot or leg passing beside and below a hurdle. The rule-history table lists a TR22.6 revision as approved and effective on 2025-12-03.
Two fictional hurdle falls
In a fictional race, a runner clears the hurdle with the legs above its top plane; the bar falls after a light trail-leg brush, and no other athlete is affected. The fall alone would not establish a disqualification. In a second fictional case, a runner knocks the bar down with a hand. That contact is a ground listed in TR22.6.2. These examples explain the factors; they do not decide a real referee’s ruling.
Related questions
Does the rule still require officials to prove a runner acted deliberately?
The Comments say the former reference to deliberately knocking down a hurdle was removed. The current rule lists objective contact and interference conditions.
Can a hurdle fall without affecting another runner?
Yes. A fall alone is not automatically disqualifying. Other listed grounds, including contact by hand or the front side of the lead lower limb, can still apply.
Does a hurdle in another lane always mean disqualification?
No. The Comments say the effect on the other athlete matters. A hurdle already cleared, or a displacement without significant effect, does not necessarily lead to disqualification by itself; another rule infringement can still matter.
