Can You Be Fined or Arrested for Putting a Mexican Flag on Your Car in September? What the Law Says
During September, it is common for drivers to place Mexican flags on their vehicles as part of the celebrations for Mexico’s national holidays. However, there is a risk associated with this simple action, since it is prohibited under certain circumstances and could result in a fine or even lead to arrest.
Article 32 of the Law on the National Coat of Arms, Flag, and Anthem establishes that individuals may use the National Flag on their vehicles, provided that they respect the national symbol. The Secretariat of the Interior is the authority responsible for monitoring compliance with this legislation.
The point motorists must consider is how they place the flag. If its installation blocks visibility, distracts the driver, or creates a traffic hazard, the sanctions established by the traffic regulations of the jurisdiction where the vehicle is being driven may apply.
Therefore, before placing a flag on the windshield, mirrors, or any other part of the vehicle, it is advisable to know what the law allows and which actions can result in a traffic violation.
Does the Law Allow You to Carry a Mexican Flag on Your Vehicle?
Yes.
Article 32 of the Law on the National Coat of Arms, Flag, and Anthem states that individuals may use the National Flag on their vehicles or display it at their homes or workplaces.
The same provision establishes that, in these cases, the flag may be of any size, provided that the respect owed to the national symbol is observed.
The Secretariat of the Interior itself explains that the use of national symbols is regulated by federal legislation and that their characteristics cannot be arbitrarily altered.
So Why Can a Driver Be Fined?
The potential violation is not necessarily related to the flag itself, but rather to safety while driving.
Traffic regulations are applied locally and may establish penalties when an object placed inside or outside a vehicle prevents the driver from having an adequate view of the road or represents a distraction.
An example is Mexico City.
Article 38, section II, subsection a), of the capital’s Traffic Regulations prohibits drivers of motor vehicles from carrying objects that “obstruct the driver’s visibility or distract them.”
Therefore, a flag placed in such a way that it covers part of the windshield, makes it difficult to see the mirrors, or interferes with the driver’s field of vision can result in a traffic violation.
How Much Is the Fine for Carrying a Flag That Obstructs Visibility?
In Mexico City, violating this provision can result in a fine of 5, 7, or 10 times the UMA, in addition to one penalty point on the driver’s license.
The daily UMA in effect in 2026 is 117.31 pesos, according to the National Institute of Statistics and Geography (INEGI). This value began to apply on February 1, 2026.
Therefore, the penalties are equivalent to:
| 5 UMA | $586.55 |
|---|---|
| 7 UMA | $821.17 |
| 10 UMA | $1,173.10 |
The specific amount depends on the violation and the application of the corresponding regulations.
Important: These amounts apply to Mexico City. They should not be presented as a nationwide fine for carrying a flag in a vehicle.
What Happens if the Flag Is on the Windshield or Rearview Mirror?
This is where a problem can arise.
A flag installed on the front windshield can reduce the driver’s field of vision. Something similar can occur if it is placed on the central rearview mirror or in a way that interferes with visibility through the windows or side mirrors.
In these cases, the basis for the violation would be obstruction or distraction while driving, not the fact that it is a Mexican flag.
For safety reasons, the recommendation is to avoid any installation that reduces the driver’s field of vision.
Can the Flag Have Any Design?
No.
Although the law allows an individual to use the National Flag on their vehicle and states that it may be of any size, this does not mean that its official characteristics can be freely modified.
The Law establishes the characteristics of the National Flag, and the Secretariat of the Interior has stated that its design cannot be arbitrarily altered.
Article 56 considers it an offense, among other conduct, to alter or modify the characteristics of the National Flag established by law.
Therefore, a decoration that changes the official colors, proportions, or characteristics of the symbol could create a problem separate from the one related to traffic regulations.
Can You Also Be Fined for Using the Flag to Promote a Product?
Yes.
Federal legislation establishes a specific restriction.
Article 32 Bis states that individuals and institutions may not use the National Flag to promote their image, goods, or services.
This is different from placing a flag on a private vehicle as part of a celebration. The restriction becomes relevant when the national symbol is used for promotional or commercial purposes.
How Severe Can a Penalty Be for Violating the National Symbols Law?
Federal legislation provides for penalties that are independent of traffic fines.
Article 56 Quintus establishes that, depending on the violation and the circumstances, one or more sanctions may be imposed, including a warning, a fine of up to 10,000 times the value of the UMA, an additional fine of up to 10,000 times the UMA for each day the violation continues, and arrest for up to 36 hours.
The penalty depends on the specific conduct and on the application of the Law on the National Coat of Arms, Flag, and Anthem.
In addition, the legislation establishes that factors such as the seriousness of the conduct, the damage caused to national symbols, intent, the offender’s financial capacity, and repeat offenses are considered when determining the sanction.
How Can You Carry the Flag in Your Car Without Risking a Fine?
If you want to place a Mexican flag on your vehicle during the national holiday celebrations, these are some practical measures:
- Do not place the flag over the windshield.
- Do not cover the rearview mirror or side mirrors.
- Avoid any installation that reduces the driver’s field of vision.
- Do not place objects that could distract the driver.
- Use a flag that respects its official characteristics.
- Do not modify its colors, proportions, or elements.
- Do not use the national symbol as advertising for a product or service.
- Properly secure any exterior element to prevent it from coming loose while driving.
- Check the traffic regulations of the jurisdiction where you are driving, since provisions may vary among states and municipalities.
So, Is It Illegal to Carry a Mexican Flag on Your Car?
No.
Federal legislation expressly allows individuals to use the National Flag on their vehicles. The problem arises when its use fails to comply with applicable provisions or when the way it is placed creates a traffic violation.
In other words, carrying a flag is not, by itself, grounds for a fine.
If the flag is properly placed, respects the characteristics of the national symbol, and does not affect visibility or driving safety, Article 32 permits its use.
The figure of up to 1,173.10 pesos applies to the situation involving obstructed visibility established in Mexico City’s Traffic Regulations for 2026. It is not a nationwide fine for carrying the flag.
Before driving on highways or through city streets during September, the simplest rule is to keep the driver’s field of vision clear and place the flag safely. This allows people to celebrate the national holiday month without confusing authorization under federal legislation with the traffic rules that each jurisdiction applies on its roads.
