Car Hire in Mexico: What to Know Before You Drive

Before you leave the rental car park

Driving conditions in Mexico vary considerably between modern toll motorways, large cities, coastal routes, mountain roads and rural areas. A few checks before departure can prevent problems later.

• Confirm the fuel type: check whether the vehicle uses petrol, diesel, electricity or another fuel.
• Find the controls: locate the lights, indicators, wipers, hazard lights, demister, horn and parking brake.
• Check existing damage: make sure visible damage is recorded and consider taking your own photographs.
• Check the tyres: look for obvious damage and confirm whether a spare wheel or puncture-repair kit is supplied.
• Ask about tolls: check whether the vehicle has an IAVE or other electronic toll TAG and how charges are handled.
• Mexico City itinerary: ask whether the vehicle is affected by Hoy No Circula restrictions.
• Save roadside-assistance details: keep the rental provider's assistance number accessible.

Treat the speed limit as a maximum, not a target

Road, traffic and weather conditions can require a substantially lower speed than the signed maximum.

• Slow down for poor road surfaces, bends and limited visibility.
• Increase following distance in heavy rain.
• Be prepared for slow vehicles entering or leaving rural roads.
• Reduce speed substantially where pedestrians or animals are near the carriageway.

Watch for topes

Speed humps are extremely common in Mexican towns and villages and are usually referred to as topes.

• Some are clearly signed and painted.
• Others can be difficult to see, particularly at night.
• Reduce speed when entering towns and villages.
• Watch the behaviour of vehicles ahead because sudden braking can indicate an approaching tope.
• Crossing a large tope too quickly can damage a rental vehicle.

Cuota and libre roads

On longer journeys you will often have a choice between a tolled cuota route and an untolled libre route.

• Cuota: a toll road.
• Libre: an untolled road.
• Tolled routes are often built to a higher standard and can offer faster long-distance journeys.
• Many tolled federal routes use a D after the route number, although road signs should always be checked.
• Journey planning should consider road conditions and current travel advice as well as distance.

Mexico has an extensive network of toll roads

Several organisations operate Mexican toll roads. CAPUFE is the largest national toll-road operator but does not operate every tolled motorway.

• Toll prices depend on the road, toll plaza and vehicle class.
• Payment arrangements differ between operators.
• Unless your rental provider confirms an electronic arrangement, carry Mexican pesos for toll plazas.
• Do not assume that every toll plaza accepts the same cards or payment methods.
• Keep receipts where provided until the rental is fully settled.

IAVE electronic toll payment

IAVE is CAPUFE's electronic toll-payment system. A compatible TAG attached to the vehicle can automatically pay at participating toll plazas.

• Ask whether the rental vehicle has an active electronic toll TAG.
• Confirm whether toll charges are billed automatically after the rental.
• Do not remove or replace a TAG supplied with the vehicle.
• IAVE works on CAPUFE's own network and interoperable participating roads, but should not be assumed to cover every toll road.
• Use the correct toll lane for the payment method available in your vehicle.

Roadside assistance

Your first contact after an ordinary rental-car breakdown should normally be the roadside-assistance number in the rental agreement.

• Keep the provider's telephone number somewhere accessible.
• CAPUFE provides roadside assistance on the roads it operates.
• CAPUFE's assistance number is 074.
• Mexico's Ángeles Verdes service also provides tourist road assistance on many routes.
• If you are stopped on a high-speed road, move as far away from moving traffic as safely possible.

Check Hoy No Circula before driving in Mexico City

Mexico City and the surrounding metropolitan area operate the Hoy No Circula programme to restrict some vehicles according to registration and emissions classification.

• The rule that applies can depend on the vehicle's registration, emissions classification and day of the week.
• Vehicles registered outside Mexico City and the State of Mexico can face additional restrictions.
• Environmental contingencies can introduce stricter temporary restrictions.
• Current rules can therefore differ from information in an older travel guide.
• Ask the rental company whether the particular vehicle can be driven on your planned day and route.

Plan long road journeys carefully

Mexico is a very large country and driving conditions vary greatly by state and region.

• Check current travel and road information before a long intercity journey.
• Use established main routes where practical.
• Current travel guidance recommends using toll roads where possible on many longer journeys.
• Plan to complete unfamiliar intercity routes during daylight where practical.
• Make sure you have enough fuel before entering remote areas.

Night driving can be more demanding

• Road lighting varies considerably outside towns.
• Topes can be particularly difficult to see after dark.
• Pedestrians, cyclists and animals may be hard to see.
• Road damage can be less visible at night.
• Where practical, plan unfamiliar long-distance driving for daylight.

Heavy rain and tropical storms can disrupt roads

Mexico can experience intense rainfall and tropical cyclones, particularly during the hurricane season.

• Heavy rain can cause flooding and landslides.
• Do not drive through flood water where the depth or current is uncertain.
• Mountain routes can be affected by rockfalls or landslides.
• Follow local authority instructions when severe weather affects your route.
• Be prepared to change the itinerary if a road is closed.

If you are stopped for a traffic offence

• Remain calm and follow lawful instructions.
• Keep your driving licence and rental documentation accessible.
• If a fine is issued, ask for written documentation.
• Use the official payment procedure stated on the citation.
• Do not offer unofficial cash payments.
• Contact the rental provider if the vehicle or rental documents are involved.

Drink-driving rules vary by jurisdiction

Alcohol limits and enforcement arrangements can differ between Mexican states and cities, so a single nationwide visitor limit should not be assumed.

• Police can carry out alcohol enforcement.
• Local limits may be stricter than a visitor expects.
• Penalties can include fines, detention and vehicle-related sanctions.
• Do not use a legal threshold as a drinking target.
• The simplest approach with a rental car is zero alcohol before driving.

Driving licence requirements for visitors

Documentation requirements can depend on the licence that you hold and on the rental company's own conditions.

• Carry your original valid national driving licence.
• The rental company may require an International Driving Permit or additional identification.
• An International Driving Permit is a translation and does not replace the underlying driving licence.
• Check the exact documentation requirement before travelling, particularly if your licence is not in Spanish or English.
• Rental providers can apply minimum-age and minimum licence-holding periods.

Irish driving licence holders

Irish visitors should carry their current full Irish driving licence and check the rental provider's documentation requirements before travelling.

• NDLS issues International Driving Permits to eligible Irish licence holders.
• An IDP, where required by a provider or authority, must be carried together with the original Irish licence.
• IDP recognition differs between countries, so NDLS recommends checking the requirements for the destination before travel.
• Do not rely on the IDP as a substitute for the Irish licence.

Before returning the hire car

• Confirm the exact branch or airport return location.
• Refuel or recharge according to the rental agreement.
• Keep the final fuel receipt if required.
• Allow substantial extra time in Mexico City and other congested urban areas.
• Confirm how outstanding electronic toll charges will be handled.
• Remove personal belongings and check the glovebox, door pockets and luggage area.
• Consider photographing the vehicle, mileage and fuel level at return.
• Keep the rental paperwork until the deposit or card pre-authorisation has been released.
