California C-32 Parking and Highway Improvement Exam

Free study guide and practice questions for the California CSLB C-32 Parking and Highway Improvement exam — pavement striping and markings, curb colors, ADA parking, surface seals, sport courts, pavement repair, and work-zone safety, built from the public California MUTCD, Vehicle Code, federal ADA Standards, and FAA and OSHA materials.

Passing score 72%Practice bank 60Topics 7

The C-32 Parking and Highway Improvement contractor installs and maintains the surface features of roadways and parking facilities — pavement striping and markings, raised markers, curbs, wheel stops, surface seals, and incidental pavement repair — including parking lots, highways, sport courts, and airfields. It requires passing this trade exam in addition to the Law & Business exam.

The CSLB exam outline weights the trade exam across: Planning & Estimating (~23%), Surface Coatings (~20%), Striping, Markers & Wheel Stops (~14%), Special Applications (~8%), Incidental Pavement Repair (~8%), and Safety (~27%).

This is one of the cleanest exams to study from public sources: pavement-marking colors come from the California MUTCD, curb colors from the California Vehicle Code (§21458), accessible parking from the federal ADA Standards, airfield markings from FAA advisory circulars, and work-zone safety from the MUTCD and Cal/OSHA — the same material behind the C-31 and C-12 trades. Work through the topics, then take a full timed practice exam.
