What happens if a ball in play at rest is moved by an outside agency?  This is one of the answered questions of the new long drive rules established for first time by Long Drivers European Tour (LDET) in order to regulate this sport practice around the continent. The clubs, balls, tees and behavior are contained in this new regulation. LDET Rules are self adapted following the standard of R&A (, the governing body of golf worldwide except the United States ( and Mexico.

It is important to notice that players are responsible for knowing the rules and the possible penalties for breach of condition. This is considered to be justifiable in terms of protecting the interests of the majority of golfers who wish to play in accordance with these guidelines and will gain maximum enjoyment from the game.

* This is the version 1.4 of the LDET rules.

* The LDET thanks Marc Autret & Eric Houballah for their collaboration and their website

New Rule Change Effectively Immediately

All clubs used in competition must conform with the USGA Rules of Golf which limits length to a maximum of 48”.

March 9th 2017.- Like the World Long Drive Association (WLDA) announced a few weeks ago, a rule has changed as it relates to club length that will go into effect immediately for all future LDET (Long Drivers European Tour) tournaments. The new rule states that all clubs used in competition must conform with the USGA® Rules of Golf (Appendix II, 1c), which limits club length to a maximum of 48”. The rule will be upheld at all the events through the use of a Measuring Tool for measuring club length. LDET will measure and check all the clubs during the registrations.

The rule change in effect will reduce the previous maximum length allowed (50") and is being implemented to allow Long Drive competitors to be held to the same standard of competition as Tour professionals in accordance with the USGA.
