The incident happened on the eastbound Interstate 8 connector to northbound SR-163 in Mission Valley, police said.
A man on a motorcycle, who has not yet been identified, thought he had been cut off by another driver and started an argument, police said. The motorcyclist told the driver he had a gun.
