Question 1

What BAC threshold applies to a driver under 21 in Mississippi, and when does that stop applying?

Accepted Answer

0.02% under Zero Tolerance, unless their BAC actually reaches 0.08% or more, which is charged as a standard DUI instead — Mississippi's Zero Tolerance law sets the threshold at 0.02% for a driver under 21, unless that driver's BAC actually reaches 0.08% or more, in which case it's charged as a standard DUI, not Zero Tolerance.

Question 2

What happens immediately if a Mississippi driver refuses a breath or chemical test?

Accepted Answer

Their license is surrendered for a temporary permit valid only 45 days, plus a 90-day administrative suspension — Refusing a breath or chemical test means immediately surrendering your license for a temporary permit valid only 45 days, plus an administrative suspension of 90 days that increases for subsequent refusals.

Question 3

How long is the temporary permit valid for a Mississippi driver who tests at or over the legal BAC limit?

Accepted Answer

30 days — Testing at or over the legal BAC limit means surrendering your license for a temporary permit valid only 30 days while the case is reviewed -- shorter than the 45-day temporary permit given for a test refusal.

Question 4

What penalties apply to a first Mississippi DUI conviction for a driver 21 or older?

Accepted Answer

A $250-$1,000 fine, up to 48 hours in jail, and a 120-day license suspension — A first DUI conviction (21+, 0.08% or higher) brings a $250-$1,000 fine, up to 48 hours in jail, and a 120-day license suspension; a second conviction within five years brings harsher penalties including a 1-year suspension.

Question 5

What happens after release from custody for a third Mississippi DUI conviction within five years?

Accepted Answer

3 years on an interlock-restricted-only license, following 1-5 years in custody as a felony — A third DUI conviction within five years is a felony carrying $2,000-$5,000 and 1-5 years in custody, followed by 3 years on an interlock-restricted-only license after release; a fourth or later offense carries a 10-year interlock period instead.

Question 6

How do Mississippi's Zero Tolerance DUI penalties escalate for a driver under 21?

Accepted Answer

From a $250 fine and 120-day suspension on a first offense to up to $1,000 and a 2-year suspension (or until age 21, whichever is longer) on a third offense within five years — Zero Tolerance DUI penalties (under 21, BAC 0.02%-0.079%) escalate from a $250 fine and 120-day suspension on a first offense to up to $1,000 and a 2-year suspension (or until the driver turns 21, whichever is longer) on a third offense within five years.

Question 7

What happens if a first-offense Mississippi DUI conviction is combined with a refusal of the breath or chemical test?
