The Daily Herald reports that the toll-road agency will test "dynamic messaging signs" beginning with Interstate 90, the Jane Addams Tollway.
Executive Director Kristi Lafleur says the signs allow for a "great opportunity to communicate more clearly with the public and use a broader array of messaging."
The Federal Highway Administration must approve. Signs with colors and graphics can run as high as $160,000.
Officials say other states have found higher-tech signs present images that are recognized more easily. For example, a skidding car would show up with a warning of slippery conditions.
Orange signs for construction work well. Flops include handcuffs as a warning against drunk driving.
