Today and tomorrow it's legal to purchase Safe-and-Sane fireworks in Clark County from a licensed vendor. But once July Fourth is over, it becomes illegal again in Clark County to purchase any fireworks, including Safe-and Sane. All other types of fireworks are illegal to purchase in Clark County year-round.
The best way to fight charges of illegal fireworks laws in Nevada depends on the facts of the case. A common defense is that the fireworks didn't belong to the defendant and that he/she had no idea they were there. First offenses are frequently dismissed if the defendant agrees to pay a court fine.
