Car insurance in Myrtle Beach costs more than most people expect for a city of roughly 35,700 permanent residents, until they spend a Saturday afternoon stuck on Kings Highway. Full coverage here averages around $2,760 a year against South Carolina's $1,890 statewide figure, and minimum coverage runs near $1,860 versus $728.
That gap isn't random. It's the price of sharing a narrow coastal grid with roughly 20 million visitors a year.
Why Highway 17 Sets the Baseline
US-17, known locally as Kings Highway, has the dubious distinction of being the most dangerous road in Horry County. A single recent year logged more than 2,100 crashes on the corridor, with roughly 20 fatalities and close to 935 injuries attached to it.
The US-17 Bypass interchange near Surfside Beach is the worst offender, ranking as the area's most hazardous intersection with 240 crashes recorded over a recent three-year stretch. Insurers don't need a resident's personal driving record to price that risk — the corridor does it for them.
A City That Multiplies Its Population Every Summer
Myrtle Beach's year-round population sits around 35,700, but the Grand Strand draws an estimated 20 million visitors annually. Daily traffic volume on the main corridors can climb past 150,000 vehicles during peak holidays and summer weekends.
Rental cars, out-of-town drivers unfamiliar with local intersections, and bumper-to-bumper beach traffic all add claims frequency a purely residential city wouldn't generate. That seasonal churn shows up in the annual average even though most residents drive the same streets calmly the rest of the year.
What Myrtle Beach Drivers Are Required to Carry
South Carolina law sets a 25/50/25 liability floor: $25,000 in bodily injury coverage per person, $50,000 per accident, and $25,000 in property damage. That requirement doesn't change because a city sits on the coast or draws more tourists than most state capitals.
Uninsured motorist coverage at those same 25/50 limits is mandatory on every policy sold in the state, since South Carolina is a tort state and doesn't require PIP as a fallback. Underinsured motorist coverage is optional, but insurers have to offer it.
Does Your ZIP Code Change the Quote?
It can, and in Myrtle Beach the difference is sharper than in most cities. ZIP 29577 covers the dense tourist core near the boardwalk and Ocean Boulevard, where stop-and-go traffic and higher theft exposure push quotes up.
Inland ZIP 29579, around the Carolina Forest area, sees calmer residential streets and less tourist-driven congestion. Two Myrtle Beach drivers with identical coverage and driving records can land on noticeably different premiums depending on which side of town the car is garaged.
None of this means Myrtle Beach drivers are stuck overpaying. It means a rate built around a high-crash highway corridor and a population that quadruples every summer needs a fresh quote comparison more than most — not an assumption that the sticker price is fixed.
