Observed UFO Sighting which stopped my moving vehicle on a lonely, tree lined road.

On a late summer evening in either 1966 or 67...I believe it was 1966;  I was driving my 1966 Chrysler down County Rd. in District Heights, MD, headed to my relatively new apartment complex, by the name of Kennedy Woods!  At that time, the area road was a very wooded, lonely road and a very sparsely populated area.
All of a sudden a ‘quiet, oval saucer  shaped object confronted me hovering directly above my car windshield, with extremely bright lights all around. Approximately 300 to 400 ft. above me.  Whatever the object was, it ‘stopped’ my automobile, in the middle of the road, and just sat there for several minutes, making absolutely no noise! Then, just as it appeared, it lifted up and was completely gone.
Not a sound had I heard during the entire sighting. Then my car engine began to run again, and I hurried to my apartment, quiet sure of what I had seen. A Prince George’s County police officer and his family lived in the apartment directly above me and I immediately went to their apartment to report what I had seen.
The police officer’s wife was home and immediately tried to call her husband at the Police station. Finally, upon reaching him and reporting my incident, he informed us that the reason she had trouble getting through was there were ‘dozens’ of calls coming into the station of ‘Sightings’! Then I was sure that what I had observed was a true UFO sighting.
Witness indicates that date of incident is approximate.  PD
