Wrong way and one-way traffic signs at the Magnolia Boulevard off-ramp from northbound Hollywood Freeway (State Route 170) in North Hollywood, California.

This sign arrangement is installed by Caltrans on both sides of all California freeway off-ramps to discourage wrong-way drivers. Because this arrangement is not in compliance with the Manual on Uniform Traffic Control Devices, the U.S. federal government will not pay for installation of these signs, so Caltrans has to pay for them.

Notice how the signs are clustered together and are placed close to the ground; this is a deliberate design decision to attract the attention of drunk drivers.
