DAGSBORO — A 21-year-old Seaford man died after being struck by a vehicle on DuPont Boulevard on Monday night, Delaware State Police spokeswoman Master Cpl. Heather Pepper said.

The man had exited his vehicle, which was parked on the roadway’s shoulder, authorities said. He was wearing dark-colored clothing and was not using a light. The operator of a 2007 Honda Accord, a 31-year-old Frankford man, was unable to see the victim, and his vehicle struck him in the left lane, police said.

After the collision, the driver came to a controlled stop just south of the scene.

The victim was transported by helicopter to ChristianaCare, Newark, where he was pronounced deceased. Identification is pending notification of next of kin.

The driver of the Accord and his 5-year-old passenger were not injured.

DuPont Boulevard was closed for approximately three hours, while the investigation was completed and the scene was cleared.

The DSP Troop 7 Collision Reconstruction Unit is investigating the collision. Anyone with information is asked to contact Cpl./3 K. Argo at 644-5020. Information may also be provided by calling Delaware Crime Stoppers at (800) TIP-3333 or visiting here.

Citing the warmer weather and an increased number of pedestrians around roadways, DSP issued the following safety tips:

• Be visible. When walking at night, wear bright-colored clothing. Use a flashlight or reflective items.
• Never dart out. Cross streets at crosswalks or intersections when possible. This is where drivers expect pedestrians.
• If your vehicle breaks down, turn on your flashers and stay with your vehicle until assistance arrives.
• Use pedestrian push buttons and wait for the walk signal to cross.
• Take your time to cross. If a crosswalk or intersection is not available, locate a well-lit area and wait for a gap in traffic that allows you enough time to cross safely. Continue to watch traffic as you cross.
• Make eye contact with drivers as they approach. Never assume a driver sees you.
• Walk on sidewalks whenever they are available. Walk on the shoulder facing traffic if no sidewalk is available.
• Keep alert at all times. Don’t be distracted by cellphones and electronic devices that take your eyes (and ears) off the road.
• Avoid alcohol and drugs. They impair your judgment and coordination.
