What Does Pair Mean in French Traffic Law?

In French driving terminology, the word pair translates to even. In the context of the Code de la Route (French Highway Code), this concept is primarily applied to parking regulations. Many narrow streets in French towns do not have enough space to allow parking on both sides simultaneously. To prevent traffic bottlenecks and ensure equal access for residents, local authorities implement alternating parking rules based on house numbers and calendar dates.

Understanding whether a number is even (ending in 0, 2, 4, 6, or 8) is critical because it tells you exactly where you are legally allowed to park during specific times of the month.

The Rules of Semi-Monthly Alternating Parking

Semi-monthly alternating parking, known in French as stationnement alterné semi-mensuel, is a regulation where parking is permitted on only one side of the street at a time, switching halfway through the month. This rule is governed by two main periods:

• First half of the month (1st to the 15th): Parking is allowed exclusively on the side of the street with odd-numbered buildings (impair).
• Second half of the month (16th to the last day): Parking is allowed exclusively on the side of the street with even-numbered buildings (pair).

When a street is subject to this rule, parking on the wrong side during either period is considered an infraction, resulting in a fine and the potential impounding of your vehicle.

The Critical Changeover Period

One of the most common areas of confusion for learners—and a frequent target for trick questions on the French driving theory exam—is the transition between these two periods.

You do not wait until midnight on the 15th or the last day of the month to move your vehicle. Instead, the law mandates a specific changeover window:

• On the 15th of the month (transitioning to the even period) and on the last day of the month (transitioning to the odd period), you must move your vehicle between 8:30 PM and 9:00 PM.
• Moving your vehicle during this 30-minute window ensures that the street is clear and ready for the next phase starting the following morning.

Deciphering alternating parking signs

On the theory exam, you will encounter specific signs indicating alternating parking. A blue, circular sign with a red border, a red diagonal slash, and the numbers '1-15' or '16-31' indicates the restrictions:

• Sign with '1-15': Parking is prohibited on this side of the street from the 1st to the 15th of the month.
• Sign with '16-31': Parking is prohibited on this side of the street from the 16th to the end of the month.

By carefully reading the date provided in the exam question prompt, you can easily determine which side of the street is off-limits.
