Every now and again we learn about some jokester who thinks it’s funny to change the messages on those electronic road signs used to warn road users of hazards down the road. They apparently get a kick out of displaying ridiculous messages.

Most recently, jokesters in a handful of states have “tinkered” with such signs, getting them to present warnings about zombies. Among the messages: “Daily Lane Closures Due To Zombies,” “Caution Zombies Ahead,” and “Zombies In Area! Run.”

While such pranks may seem amusing, they cause create dangerous situations. “Joke” messages distract road users from heeding legitimate safety information.

Electronic road signs play an important role in highway safety and traffic operations. They are intended to attract motorists’ attention and provide important information to protect motorists, highway crews, and emergency response personnel.

Jokes and pranks have their place, but not in road traffic safety.

There is nothing humorous about deaths, injuries, and property damage resulting from vehicle crashes.
