SIOUX FALLS, SD (KELO) -- South Dakota law enforcement officers are reminding drivers of important safety precautions to take this week with many trick-or-treating events underway ahead of Halloween. "Thousands of pedestrians will be trick or treating on Halloween. Please be vigilant when driving. We want you to remember, if you choose to celebrate, don't drink and drive. Please dedicate a sober driver and also put your phone down. Don't drive distracted with so many children walking and crossing streets. Let's work to keep our communities safe," Lt. Casey Kenrick of the Pennington County Sheriff's Office said via Facebook. It's also important to make sure your kids are visible to drivers while they're out trick or treating. The Consumer Product Safety Commission says costumes should be brightly-colored or trimmed with reflective tape and be made from flame-resistant fabric. Avoid long and baggy costumes to prevent trips and falls. You should also put reflective tape on treat bags and check to see that the candy is individually wrapped. Also, masks should have eye holes large enough to allow full visibility.
