• TURN RESTRICTIONS• SPEED LIMITS• IMPROVEMENTS

TURN RESTRICTIONS• SOUTHBOUND US 101 - MILLER

CREEK ROAD OFF RAMP• MARINWOOD AVE./MILLER CREEK

RD. INTERSECTION• 6:00 am to 10:00 A.M.

SPEED LIMITS• MILLER CREEK ROAD• LAS GALLINAS AVENUE• BLACKSTONE DRIVE

RAISE THE SPEED LIMIT?But… why??

Two different kinds of speed limits

Maximum Prima Facie

Maximum Speed Limits Written into state law No justification (survey) needed to

enforce w/ radar State maximum for different

roadway designs 55: Max on 2-lane, undivided

roads 65: Max on multi-lane, divided and

undivided roads 70: Max on certain rural freeways

in California

22349(a/b) and 22356(b) CVC

Prima Facie Speed Limits Anything lower than the state

maximums require justification CHP cannot use radar to enforce PF

speed limits without justification Justification is county Engineering and

Traffic Survey (ETS)40802 CVC

Engineering and Traffic Survey

85th percentile 85% of vehicles driving this

road go this speed or lower Speed limit is set to nearest 5

MPH increment below 85th percentile speed

Anything lower is a speed trap

CHP must still articulate in court why speed was unsafe for conditions

CHP cannot enforce a 25 MPH speed limit on Las Gallinas Ave with no ETS

ETS sets safe speed at 30 MPH ANY radar enforcement would be a speed

trap and illegal Vehicle at 40? CHP can do nothing about

it.

Why not keep the 25 MPH on Las Gallinas Ave?

Why raise the limit to 30 MPH on Las Gallinas?

85% of vehicles safely use Las Gallinas Ave at this speed already

Limit would still be 25 at Miller Creek School while children are present

Vehicle at 40? CHP can cite.
