SC Route Restricted License Employer Letter Requirements

South Carolina's Route Restricted License application requires a completed SCDMV application form, SR-22 proof of insurance for DUI and uninsured suspensions, and a signed employer verification letter confirming your job-related driving need. For DUI cases, you must also provide ignition interlock device installation confirmation before the license issues. The employer letter is the fulcrum: SCDMV uses it to define approved routes and time windows. Generic letters stating "this employee needs to drive for work" trigger denials because they give the agency no route or hour boundaries to write into the restriction. The letter must specify your work address, shift start and end times, and whether your job requires driving during work hours beyond the commute. The $100 application fee is non-refundable. If your employer letter lacks the required specificity, SCDMV returns the application without issuing the license and you resubmit with the fee paid again.

SCDMV does not publish a mandatory employer letter template, which creates confusion. The letter must include your employer's business name, address, and contact phone number on company letterhead. It must state your position, your work schedule including days of the week and shift hours, and your work location address. The critical element: route specificity. The letter should state your home address and confirm that your job requires you to drive from home to the work location and back. If your job requires driving during work hours, the letter must describe that need explicitly: delivery driver covering specific ZIP codes, home health aide visiting client addresses, sales role requiring client site visits. Vague language like "occasional business travel" does not satisfy SCDMV's route-definition requirement. The letter must be signed by a manager, HR representative, or business owner with authority to verify employment. SCDMV may call the phone number on the letterhead to confirm. If the contact cannot verify your employment or the details in the letter, the application will be denied.

South Carolina's Route Restricted License is not a blanket hardship license. The restrictions printed on the license are drawn directly from your employer letter and the approved-purposes you listed on the application. Most licenses restrict driving to the direct route between home and work during a defined time window that brackets your shift hours. If your shift starts at 7:00 AM and ends at 3:30 PM, the time restriction typically allows driving from 6:00 AM to 4:30 PM on work days. If you work Monday through Friday, Saturday and Sunday driving is prohibited unless you also documented a medical appointment need or another approved purpose on the application. Driving outside the approved route or time window is treated as driving under suspension. South Carolina law enforcement can verify route restrictions by calling dispatch during a traffic stop. If you are stopped on a road that is not part of the direct home-to-work route defined in your employer letter, you will be cited for violation of the restricted license terms and the license will be revoked.

South Carolina's Emma's Law mandates ignition interlock devices for all DUI offenders as a condition of any restricted driving privilege, including first offenses. If your suspension stems from a DUI or DUAC conviction, you must install an IID with an SCDMV-approved vendor before the Route Restricted License is issued. The IID installation confirmation must be submitted with your Route Restricted License application. SCDMV will not process the application without proof that the device is already installed and monitoring has begun. The device remains required for the full duration of the restricted license period and typically extends into the reinstatement period. IID costs stack on top of the Route Restricted License fee: installation typically runs $75 to $150, monthly monitoring and calibration fees run $60 to $90 per month, and removal costs another $50 to $75. For a two-year restricted license period with IID, total device costs approach $1,600 to $2,300 before premium impacts.

DUI and uninsured motorist suspensions in South Carolina require SR-22 proof of insurance before SCDMV will issue a Route Restricted License. The SR-22 is not a separate policy: it is a filing your insurer submits electronically to SCDMV certifying that you carry at least the state minimum liability coverage ($25,000 per person, $50,000 per accident for bodily injury, $25,000 for property damage). You must maintain continuous SR-22 coverage for the full filing period, typically three years from the conviction date for DUI cases. If your policy lapses or cancels, the insurer notifies SCDMV electronically and your Route Restricted License is suspended immediately. Reinstatement after an SR-22 lapse requires paying a new reinstatement fee and restarting the filing period clock in most cases. Non-owner SR-22 policies cover drivers who do not own a vehicle but need to meet the filing requirement to obtain a Route Restricted License. Premiums for non-owner SR-22 typically run $40 to $80 per month depending on driving record and county. Standard auto policies with SR-22 endorsement for owned vehicles typically add $15 to $35 per month to the base premium, but the underlying premium for high-risk drivers post-DUI can reach $180 to $300 per month.

Some employers refuse to sign letters supporting Route Restricted License applications due to liability concerns or company policy prohibiting employees with suspended licenses. When this happens, you have no leverage: SCDMV will not issue the license without employer verification, and South Carolina law does not require employers to accommodate restricted-license holders. If your employer will not provide the letter, you cannot obtain the Route Restricted License for that job. Your options narrow to finding a new employer willing to sign the verification letter, arranging alternative transportation (rideshare, carpool, public transit where available), or waiting out the full suspension period before reinstatement. For commission-based workers, gig drivers, or self-employed individuals, SCDMV typically requires business registration documents, a signed affidavit describing the work need and driving routes, and sometimes proof of client contracts or scheduled appointments. The self-certification threshold is higher because the agency has no third-party employment verifier to call.

South Carolina's Route Restricted License does not authorize commercial driving, even for the job that requires the commute. If you hold a commercial driver's license and your employer letter describes a CDL-required position, the Route Restricted License will explicitly exclude commercial vehicle operation. This creates an employment trap for CDL holders: you can drive to the job site in a personal vehicle under the Route Restricted License, but you cannot perform the job duties that require operating a commercial vehicle once you arrive. Most trucking, delivery, and transit employers will not retain drivers who cannot operate commercial vehicles, making the Route Restricted License functionally useless for CDL-dependent jobs. If your suspension disqualifies your CDL under federal or state regulations, reinstatement of the commercial license follows a separate process from the Route Restricted License. The restricted license does not shorten the CDL disqualification period and in some cases the CDL remains suspended even after the personal driver's license is reinstated.
