Whether or not you are in costume, you can find a Halloween event to attend in The Going Out Guide. (Evy Mages — For The Washington Post)

Drivers have a lot on their minds as they navigate through their first commutes after Hurricane Sandy’s departure, but I hope they’ll remember to watch out for trick-or-treaters on their way home.

Halloween hazards will combine with the dangers of some darkened signal lights, downed trees and power lines, and patches of wet leaves that can cause skids.

Slow down. Speeding makes it more difficult to stop unexpectedly. Be especially cautious between 4 and 9 p.m., the hours when children are most likely to be out. Enter and exit driveways slowly. Watch for children running across streets or darting out from between parked cars.

Pedestrians, including parents who will be shepherding little monsters, should be mindful of the increased risks in their neighborhoods because of storm debris.

Look left, right and left again before crossing the street; cross at crosswalks or intersections; avoid dark clothing; and use reflective devices such as vests and blinking lights; avoid costumes that may impair vision; make eye contact with drivers when crossing streets; watch for speeding cars.

The Capital Weather Gang rates Halloween as a “go” in the D.C. area. Skies will be mostly cloudy. Breezes may be up to 15 mph, and there’s a slight chance of a shower.

Leesburg cancels parade

The Post’s Caitlin Gibson reports: A popular Loudoun County Halloween parade sponsored by the Leesburg Kiwanis has been cancelled in the aftermath of Hurricane Sandy.

The well-attended parade has taken place every year since 1957, following a route along King Street in the historic downtown. Suzanne Wright, secretary for the Kiwanis, said local officials were concerned that there would not be enough personnel available to handle the parade and storm cleanup responsibilities.

SoberRide program

This tip is strictly for the adults. The SoberRide program of the Washington Regional Alcohol Program will again offer free taxi rides home to travelers who think they’ve had too much to drink on Halloween night and don’t want to risk driving.

The program will run from 10 p.m. Wednesday to 4 a.m. Thursday. A cab ride home will be free up to the equivalent of a $30 fare for passengers who call 800-200-8294 (TAXI).

High heels in Dupont Circle

The High Heel Race along 17th Street NW, a Halloween season tradition, had to be postponed because of Hurricane Sandy. But it has been rescheduled for 9 p.m. Thursday. Expect crowding in the area just east of Dupont Circle.
