He was arrested within two minutes after making it over the bike rack, a law enforcement source said.
President Trump was inside the White House during the breach, but the intruder, who was identified as 26-year-old Jonathan Tran of California, was not able to enter the building.
The driver was detained by the Secret Service and declared his vehicle suspicious, a Secret Service spokesman said in a statement.
"Individual jumped bike rack on Pennsylvania Ave, not @WhiteHouse fence".
In the earlier one, a man was spotted about 12:40 p.m.in a prohibited area on the sidewalk in front of the North Lawn of the White House, according to a D.C. police report. Secret Service arrested the man for unlawful entry and searched his vehicle, which was located on the corner of 15th and I Streets NW. Trump was inside the residence at the time. "We've got a lot of good men and women who are working hard there", Chaffetz said.
"That's why we spend billions of dollars on personnel and dogs and technologies and fences and undercover people and video surveillance", Mr Chaffetz said.
The White House has a complex web of security in its different zones, with the system mostly relying on infrared and microwave technology to trigger alarms - but these can be subject to malfunction and false activation.
The incident occurred at the vehicle check point at 15th and E Streets N.W. It does not give access to the White House grounds, but only authorized vehicles are permitted to pass.
