Summary

Mississippi has never enacted a statute authorising sobriety or driver licence checkpoints. The words sobriety and safety checkpoint return nothing in the Mississippi Code, and the single traffic provision that mentions a roadblock, Miss. Code Ann. Section 63-15-4(3), only assumes the practice exists while defining it as a stop where all passing motorists are checked as a method to enforce traffic laws. That definition matters, because the same subsection forbids stopping or detaining any driver solely to verify insurance unless the stop is part of such a roadblock. A separate subsection stops officers from looking at anything on your phone except the insurance card image.

(3) Upon stopping a motor vehicle at a roadblock where all passing motorists are checked as a method to enforce traffic laws or upon stopping a motor vehicle for any other statutory violation, a law enforcement officer, who is authorized to issue traffic citations, shall verify that the insurance card required by this section is in the motor vehicle or is displayed by electronic image on a cellular phone or other type of electronic device. However, no driver shall be stopped or detained solely for the purpose of verifying that the motor vehicle is covered by liability insurance in the amounts required under Section 63-15-3(j) unless the stop is part of such roadblock. If the law enforcement officer uses the verification system created in Section 63-16-3 and receives a response from the system verifying that the owner of the motor vehicle has liability insurance in the amounts required under Section 63-15-3(j), then the officer shall not issue a citation under this section notwithstanding any failure to display an insurance card by the owner or operator. ... (6) No law enforcement officer may access any function, feature or other electronic image on a person's cellular phone or other type of electronic device when enforcing the provisions of this section except for the electronic image of an insurance card shown to the officer.

Full Breakdown

Start with the search results, because the absence is the finding. A full-text search of the Mississippi Code 1972 Annotated returns zero sections for sobriety, zero for safety checkpoint and zero for driver license checkpoint. The word checkpoint appears once, in Miss. Code Ann. Section 49-15-31, a marine resources provision that has nothing to do with roads. The word roadblock appears in one section only: Section 63-15-4, the compulsory liability insurance card statute. Mississippi checkpoints therefore do not rest on an enabling act the way, say, a permit scheme would. The Legislature has legislated around them rather than for them.

What Section 63-15-4(3) does supply is a statutory description of what a lawful Mississippi roadblock looks like. The subsection opens on stopping a motor vehicle at a roadblock where all passing motorists are checked as a method to enforce traffic laws. That is the only definition of a roadblock anywhere in the Mississippi traffic code, and it carries the feature that matters most to a driver: every passing vehicle, not a selection. A stop that picks out particular cars is not the thing the subsection is describing.

The subsection then does real work. At such a roadblock, or on any other stop for a statutory violation, an officer authorised to issue traffic citations must verify that the insurance card required by Section 63-15-4 is in the vehicle or displayed as an electronic image on a phone or other device. Immediately afterwards comes the limit: no driver shall be stopped or detained solely for the purpose of verifying that the vehicle is covered by liability insurance in the amounts required under Section 63-15-3(j), unless the stop is part of such roadblock. In other words, in Mississippi the all-motorists roadblock is the one setting in which an insurance-only stop is permitted at all.

The third sentence of subsection (3) is a safe harbour worth knowing. If the officer uses the vehicle insurance verification system created by Section 63-16-3 and gets a response confirming that the owner carries liability insurance at the Section 63-15-3(j) limits, the officer shall not issue a citation under the section, notwithstanding any failure by the owner or operator to display a card. Producing nothing is not automatically a ticket when the state database answers for you.

Subsection (6) is a rare piece of Mississippi drafting about phones. No law enforcement officer may access any function, feature or other electronic image on a person cellular phone or other electronic device when enforcing the section, except for the electronic image of an insurance card shown to the officer. Handing over a phone to show a digital insurance card at a roadblock does not open the device to anything else.

Breath testing at a Mississippi roadblock is governed by the Implied Consent Law in Chapter 11 of Title 63 rather than by any checkpoint rule. Under Miss. Code Ann. Section 63-11-5(1), a person who operates a motor vehicle on the public roads is deemed to have consented to a chemical test of breath, blood or urine, but subsection (1)(b) requires the test to be administered at the direction of an authorized officer who has reasonable grounds and probable cause to believe the person was driving under the influence. Being one of the cars in a line at a roadblock is not itself that ground. Section 63-11-5(3) also requires the officer to warn the driver, before a refusal counts, that failure to submit results in suspension of driving privileges for ninety (90) days where there is no prior conviction under Section 63-11-30, or one (1) year where there is.

Violations & Penalties

The exposure at a Mississippi roadblock is mostly documentary. Failure to have the insurance card in the vehicle, or to display it as an electronic image, is a misdemeanor under Miss. Code Ann. 00) and suspension of driving privilege for one (1) year, or until the owner shows proof of compliant liability insurance and has paid the fines, assessments and Department of Public Safety reinstatement fees. The judge must determine whether the defendant is indigent and, if so, must authorise reinstatement on proof of insurance subject to a payment plan.

Under Section 63-15-4(5), if the owner shows at the hearing or on payment that the insurance was in effect at the time of citation, the case is dismissed with prejudice and all court costs are waived. Fraudulent use of an insurance card is punished under Section 97-7-10. Refusing a chemical test after the Section 63-11-5(3) warning brings a ninety-day suspension, or one year with a prior conviction under Section 63-11-30. Driving away from a roadblock is a different matter entirely: under Miss. Code Ann. 00) or six (6) months in the county jail.

Frequently Asked Questions

Are DUI checkpoints legal in Mississippi?
The Mississippi Code neither authorises nor forbids them. There is no checkpoint or sobriety statute anywhere in the Code. The Legislature has instead written around the practice: Miss. Code Ann. Section 63-15-4(3) describes a roadblock where all passing motorists are checked as a method to enforce traffic laws and makes that setting the exception to the ban on insurance-only stops.
Can an officer stop me just to check my insurance?
No, unless the stop is part of a roadblock. Section 63-15-4(3) says in terms that no driver shall be stopped or detained solely for the purpose of verifying liability insurance at the Section 63-15-3(j) limits unless the stop is part of such roadblock. Away from a roadblock, the officer needs some other statutory violation to justify the stop before asking for the card.
I show my insurance card on my phone. Can the officer scroll through it?
No. Section 63-15-4(6) bars any law enforcement officer from accessing any function, feature or other electronic image on a person cellular phone or other type of electronic device when enforcing the section, except for the electronic image of an insurance card shown to the officer.
Do I have to take a breath test at a Mississippi roadblock?
Only when the officer has the grounds the Implied Consent Law requires. Section 63-11-5(1)(b) allows the test at the direction of an authorized officer who has reasonable grounds and probable cause to believe the driver was under the influence. If you refuse after the Section 63-11-5(3) warning, the suspension is ninety (90) days without a prior conviction under Section 63-11-30 and one (1) year with one.
What happens if I have insurance but left the card at home?
Two provisions can save you. Under Section 63-15-4(3), if the officer runs the Section 63-16-3 verification system and it confirms coverage, no citation shall issue despite the missing card. And under Section 63-15-4(5), if you later show that the insurance was in effect at the time of citation, the case is dismissed with prejudice and all court costs are waived.
Can I turn around before reaching a roadblock?
The Code says nothing about avoidance, but it does say what happens once an officer signals you. Under Miss. Code Ann. Section 97-9-72(1), a driver given a visible or audible signal to stop by an officer acting in the lawful performance of duty who has reasonable suspicion the driver has committed a crime, and who willfully fails to obey, commits a misdemeanor carrying up to One Thousand Dollars ($1,000.00) or six (6) months in jail.
