Daylight Saving Time starts up again this weekend, meaning clocks will “spring forward” an hour early Sunday morning.

While losing an hour of sleep has been shown to cause an increase in vehicle crashes, Daylight Saving Time is also an opportunity to do something safe: test and change your smoke alarm batteries.

“Working smoke alarms save lives,” the Alexandria Fire Department said on social media earlier this week. “When you spring forward on March 8, remember to test your smoke alarms and change the batteries if needed.”
