South Carolina prohibits cracks larger than half an inch in the driver’s view — the most specific numeric threshold of the eight states in this batch. Replacement runs roughly $300–$500 with a $250–$1,000 band, plus $150–$600 for recalibration where a camera sits behind the glass.

Is it illegal to drive with a cracked windshield in South Carolina?
South Carolina prohibits cracks larger than half an inch in the driver’s view — the most specific numeric threshold of the eight states in this batch.
That is the legal position; the practical one is the same everywhere — damage across the driver’s primary view is both a visibility problem and a repair disqualifier, because even a clean resin repair leaves slight optical distortion.

Does South Carolina waive the windshield deductible?
South Carolina is one of only three states that require the glass deductible to be waived. Carry comprehensive cover and your insurer must waive it for all auto glass. That is statute, not a policy option — but it is a deductible waiver rather than free work, and it depends on you holding comprehensive.
South Carolina’s waiver covers all auto glass, not just the windshield.

Can a chip be repaired instead in South Carolina?
The repair thresholds are national, not state-set. Chips up to about the size of a quarter and cracks up to roughly three inches are usually repairable; three to six inches depends on depth and position; past six inches usually means replacement.
Position overrides length: damage in the driver’s line of sight, or reaching the glass edge where the bond carries structural load, is a replacement case however short it is.
South Carolina’s half-inch rule is about legality in the driver’s view, not about repairability — a half-inch chip outside that zone is still a straightforward repair.
How long before you can drive in South Carolina?
Safe drive-away time is the point the bond can retain the glass in a crash and support airbag deployment — not full cure. Standard-cure urethane runs about 24 hours below 70°F, fast-cure about an hour, express as little as 30 minutes under controlled temperature.
Temperature is the variable that genuinely differs by location: an adhesive rated one hour at 70°F can need 8+ hours at 35°F. Ask what the figure is at the temperature they will actually be working in.
