A car is a basic necessity in New Mexico, as even the few cities are challenging to get around strictly using public transportation. Distances are considerable, but you can make excellent time on long stretches of interstate and other four-lane highways with speed limits of up to 75 mph. If you wander off major thoroughfares, slow down. Speed limits here generally are only 55 mph, and for good reason. Many such roadways have no shoulders; on many twisting and turning mountain roads speed limits dip to 25 mph. For the most part, the scenery you'll take in while driving makes the drive a form of sightseeing in itself.
Interstate 40 runs east-west across the middle of the state. Interstate 10 cuts across the southern part of the state from the Texas border at El Paso to the Arizona line, through Las Cruces, Deming, and Lordsburg.
Interstate 25 runs north from the state line at El Paso through Albuquerque and Santa Fe, then angles northeast to the Colorado line through Raton.
U.S. highways connect all major cities and towns in the state with a good network of paved roads—many of the state's U.S. highways, including large stretches of U.S. 285 and U.S. 550, have four lanes and high speed limits. You can make nearly as good time on these roads as you can on interstates. State roads are mostly paved two-lane thoroughfares, but some are well-graded gravel. Roads on Native American lands are designated by wooden, arrow-shaped signs and you'd best adhere to the speed limit; some roads on reservation or forestland aren't paved. Even in cities, you're likely to find a few surface streets are unpaved and often bumpy and narrow—Santa Fe, for instance, has a higher percentage of dirt roads than any other state capital in the nation.
Morning and evening rush-hour traffic is light in most of New Mexico, although it can get a bit heavy in Albuquerque. Keep in mind also that from most cities in New Mexico, there are only one or two main routes to Albuquerque, so if you encounter an accident or some other delay on a major thoroughfare into Albuquerque (or even Santa Fe), you can expect significant delays. It's a big reason to leave early and give yourself extra time when attempting to drive to Albuquerque to catch a plane.
Parking is plentiful and either free or inexpensive in most New Mexico towns, even Albuquerque and Santa Fe. During busy times, however, such as summer weekends, parking in Santa Fe, Taos, Ruidoso, and parts of Albuquerque can be tougher to find.
Here are some common distances and approximate travel times between Albuquerque and several popular destinations, assuming no lengthy stops and averaging the 65 to 75 mph speed limits: Santa Fe is 65 mi and about an hour; Taos is 135 mi and about 2½ hours; Farmington is 185 mi and 3 hours; Gallup is 140 mi and 2 hours; Amarillo is 290 mi and 4 hours; Denver is 450 mi and 6 to 7 hours; Oklahoma City is 550 mi and 8 to 9 hours; Moab is 290 mi and 6 to 7 hours; Flagstaff is 320 mi and 4½ hours; Phoenix is 465 mi and 6½ to 7½ hours; Silver City is 230 mi and 3½ to 4 hours; Las Cruces is 225 mi and 3½ hours; Ruidoso is 190 mi and 3 hours; Carlsbad is 280 mi and 4½ to 5 hours; El Paso is 270 mi and 4 hours; Dallas is 650 mi and 10 to 11 hours; and San Antonio is 730 mi and 11 to 12 hours.
There's a lot of high, dry, lonesome country in New Mexico—it's possible to go 50 or 60 mi in some of the less-populated areas between gas stations. For a safe trip keep your gas tank full. Self-service gas stations are the norm in New Mexico, though in some of the less-populated regions you can find stations with full service. The cost of unleaded gas at self-service stations in New Mexico is close to the U.S. average, but it's usually 15¢ to 30¢ more per gallon in Santa Fe, Taos, and certain spots off the beaten path.
All the major car-rental agencies are represented at Albuquerque's and El Paso's airports, and you can also find a limited number of car-rental agencies in other communities throughout the state.
Rates at Albuquerque's airport begin at around $25 a day and $150 a week for an economy car with air-conditioning, automatic transmission, and unlimited mileage; although you should expect to pay more during busier times. The same car in El Paso typically goes for about the same or even a bit less, again depending on the time of year.
If you want to explore the backcountry, consider renting an SUV, which will cost you about $40 to $60 per day and $200 to $400 per week, depending on the size of the SUV and the time of year. Dollar in Albuquerque has a fleet of smaller SUVs, still good on dirt roads and with much better mileage than larger ones, and they often run extremely reasonable deals, as low as $160 a week. You can save money by renting at a nonairport location, as you then are able to avoid the hefty (roughly) 10% in extra taxes charged at airports. Check the different agencies' Web sites as there are often excellent "Web-only" car rental offers.
Arroyos (dry washes or gullies) are bridged on major roads, but lesser roads often dip down through them. These can be a hazard during the rainy season, late June to early September. Even if it looks shallow, don't try to cross an arroyo filled with water —it may have an axle-breaking hole in the middle. Wait a little while, and it will drain off almost as quickly as it filled. If you stall in a flooded arroyo, get out of the car and onto high ground if possible. In the backcountry, never drive (or walk) in a dry arroyo bed if the sky is dark anywhere upstream. A sudden thunderstorm 15 mi away could send a raging flash flood down a wash in a matter of minutes.
Unless they are well graded and graveled, avoid unpaved roads in New Mexico when they are wet. The soil contains a lot of caliche, or clay, which gets slick when mixed with water. During winter storms roads may be shut down entirely; call the State Highway Department for road conditions.
At certain times in fall, winter and spring, New Mexico winds can be vicious for large vehicles like RVs. Driving conditions can be particularly treacherous in passages through foothills or mountains where wind gusts and ice are concentrated.
New Mexico has a high incidence of drunk driving and uninsured motorists. Factor in the state's high speed limits, many winding and steep roads, and eye-popping scenery, and you can see how important it is to drive as alertly and defensively as possible. On the plus side, major traffic jams are a rarity even in cities—and recent improvements to the state's busiest intersection, the Interstate 40/Interstate 25 interchange in Albuquerque, has helped to reduce rush-hour backups there. Additionally, a major highway widening and improvement along U.S. 285/84, north of Santa Fe, has also greatly smoothed the flow and speed of traffic up toward Taos.
New Mexico Department of Transportation Road Advisory Hotline (800/432–4269. www.nmroads.com.)
In the event of a roadside emergency, call 911. Depending on the location, either the New Mexico State Police or the county sheriff's department will respond. Call the city or village police department if you encounter trouble within the limits of a municipality. Native American reservations have tribal police headquarters, and rangers assist travelers within U.S. Forest Service boundaries.
