sentences:  The player is still vulnerable to any hazard for which he/she has not yet played a safety; however, after remedying it, he/she can begin to play distance cards again without using a Roll card first.If an uncorrected hazard is revealed in the battle area due to the Right of Way or a "coup-fourré" being played, and the corresponding safety is not in effect, the hazard must be corrected (and a Roll played, if necessary) in order to start moving again.Players "may" always discard, even if they have a legal play available.
