How to Pay Tolls on South Carolina Roads

Where you'll encounter tolls in South Carolina

South Carolina has two toll roads: the Charleston Harbor System (which includes the Ravenel Bridge and the Don Holt Bridge) and the Pocotaligo to Ridgeland toll road in the Lowcountry. If you cross either of these, you'll need to pay a toll. The amount depends on your vehicle type and the specific bridge or section you use.

Most drivers encounter tolls only occasionally, but if you cross regularly — for work, school, or frequent travel — understanding your payment options can save you time and money. Some methods offer discounts that others don't.

Key Takeaways

• You can pay tolls at the booth with cash or card, but this is the slowest and most expensive option.
• The Palmetto Pass is a prepaid account that gives you a 25% discount on most tolls and lets you drive through without stopping.
• If you don't have a Palmetto Pass, the toll booth will photograph your license plate and send you an invoice by mail.
• You can set up a Palmetto Pass online, by phone, or in person at customer service centers in Charleston and Beaufort.
• Rental cars and commercial vehicles have separate payment rules and may not be may be able to access for the Palmetto Pass discount.

Paying at the toll booth with cash or card

If you have no account set up, you can pay directly at the toll booth when you cross. The booth attendant will accept cash or a credit or debit card. This method works if you cross rarely, but it is the slowest option — you have to stop and wait for the transaction to complete.

Booth payment also costs more per crossing than a prepaid account. You pay the full toll rate with no discount. If you cross the Ravenel Bridge regularly, the cost difference adds up quickly over a month or a year.

The Palmetto Pass: prepaid account with a discount

The Palmetto Pass is a prepaid account linked to your vehicle's license plate. You load money into the account, and when you cross a toll road, the toll is deducted automatically. You don't stop at a booth — you drive through, and a camera reads your plate.

The main advantage is the 25% discount on most tolls. If you cross the Ravenel Bridge twice a week, that discount saves you roughly $50 to $100 per month depending on your vehicle type. The account also works across multiple crossings, so you don't have to reload after every trip.

You can set up a Palmetto Pass online at the South Carolina Toll Road Authority website, by calling their customer service line, or in person at their offices in Charleston or Beaufort. You'll need your vehicle's license plate number, a valid driver's license, and a payment method (credit card or bank account) to fund the account. The account is free to open.

Once your account is active, you can add money whenever you want. Most people set up automatic reloads so the account refunds itself when the balance drops below a certain amount. This way you never run out of funds mid-crossing.

What happens if you don't pay at the booth

If you drive through without paying and don't have a Palmetto Pass, the toll road's camera system photographs your license plate. The South Carolina Toll Road Authority uses that photo to look up your vehicle registration and mails you an invoice.

The invoice includes the toll amount plus an administrative fee. You have a set number of days to pay (usually 30). If you don't pay by the deadline, the fee increases and the account may be sent to a collection agency. Unpaid tolls can also affect your vehicle registration renewal.

This system exists as a backup for occasional drivers who genuinely didn't know about the toll, but it is not a free pass. The administrative fee makes it more expensive than paying at the booth, and far more expensive than a Palmetto Pass.

Tolls for rental cars and commercial vehicles

If you're driving a rental car, the rental company is responsible for the toll. Some rental agencies include toll costs in the rental rate; others charge you separately if a toll is incurred. Check your rental agreement before you cross, because the charges can be substantial and include processing fees on top of the actual toll.

Commercial vehicles (trucks, buses, and vehicles over a certain weight) pay a different toll rate than passenger cars. They cannot use the standard Palmetto Pass. Instead, they must either pay at the booth or set up a commercial account through the toll authority. If you operate a commercial vehicle regularly on South Carolina tolls, contact the South Carolina Toll Road Authority directly for information about commercial accounts and rates.

How to manage your Palmetto Pass account

Once your account is open, you can check your balance and transaction history online through the South Carolina Toll Road Authority website. You can also update your payment method, adjust automatic reload settings, or add a second vehicle to the same account if you own multiple cars.

If your vehicle is registered to someone else, or if you're using a borrowed car, you can still cross tolls — but the invoice will be sent to whoever owns the vehicle. If you plan to use someone else's car regularly, it's simpler to add that vehicle to your Palmetto Pass account so you're not creating invoices in their name.

If you lose your license plate or get a new one, update your Palmetto Pass account with the new plate number. The toll system matches the plate to your account, so if the number changes and you don't update it, tolls will be charged to the old plate and you'll receive invoices in the mail.

Discounts and special circumstances

The Palmetto Pass 25% discount applies to most regular crossings. However, some vehicle types or circumstances may have different rates. For example, motorcycles may have a lower toll than cars, and oversized vehicles may pay more. Check the toll authority's website or call customer service to confirm the rate for your specific vehicle.

If you have questions about a specific toll charge, a billing error, or whether you may have access to for any special rate, contact the South Carolina Toll Road Authority. They can review your account and explain any charges. If you believe you were charged incorrectly, you can dispute the charge through their customer service process.

Frequently Asked Questions

Can I use the same Palmetto Pass account for multiple vehicles?

Yes. You can add up to five vehicles to one account. Each vehicle is linked by its license plate, and tolls are deducted from the shared account balance. This works well if you have a household with multiple drivers.

What if I cross a toll road without knowing it's a toll road?

You'll receive an invoice by mail with the toll amount plus an administrative fee. You have time to pay it, but the fee makes it more expensive than paying at the booth would have been. If you cross regularly, a Palmetto Pass saves money and avoids invoices altogether.

Do I have to use a Palmetto Pass, or can I always pay at the booth?

You can always pay at the booth with cash or card. The Palmetto Pass is optional, but it's cheaper if you cross more than a few times per month. For occasional crossings, booth payment is fine.

How long does it take to set up a Palmetto Pass?

Online setup is immediate — your account is usually active within minutes. In-person setup at a customer service office takes about 15 minutes. You can start using the account as soon as it's activated.

What if my Palmetto Pass account runs out of money while I'm crossing?

The toll will still go through, and your account balance will go negative. You'll receive a notice to add funds. If you set up automatic reloads, this shouldn't happen because the account refunds itself before the balance gets too low.
