The 2018 Lucas Oil 150 was the 22nd stock car race of the 2018 NASCAR Camping World Truck Series, the third and final race of the Round of 6, and the 24th iteration of the event. The race was held on Friday, November 9, 2018, in Avondale, Arizona, at ISM Raceway, a 1-mile (1.6 km) permanent low-banked tri-oval race track. The race took the scheduled 150 laps to complete. At race's end, Hattori Racing Enterprises driver Brett Moffitt would win a dramatic race, passing eventual second-place Kyle Busch Motorsports driver Noah Gragson and eventual fourth-place ThorSport Racing finisher Grant Enfinger with just three to go to steal a victory and a berth in the Championship 4.^[1] The win was Moffitt's sixth career NASCAR Camping World Truck Series win and his fifth of the season. To fill out the podium, Harrison Burton of Kyle Busch Motorsports would finish third.

ISM Raceway – also known as PIR – is a one-mile, low-banked tri-oval race track located in Avondale, Arizona. It is named after the nearby metropolitan area of Phoenix. The motorsport track opened in 1964 and currently hosts two NASCAR race weekends annually. PIR has also hosted the IndyCar Series, CART, USAC and the Rolex Sports Car Series. The raceway is currently owned and operated by International Speedway Corporation.

The raceway was originally constructed with a 2.5 mi (4.0 km) road course that ran both inside and outside of the main tri-oval. In 1991 the track was reconfigured with the current 1.51 mi (2.43 km) interior layout. PIR has an estimated grandstand seating capacity of around 67,000. Lights were installed around the track in 2004 following the addition of a second annual NASCAR race weekend.

ISM Raceway is home to two annual NASCAR race weekends, one of 13 facilities on the NASCAR schedule to host more than one race weekend a year. The track is both the first and last stop in the western United States, as well as the fourth and penultimate track on the schedule.

Qualifying was held on Friday, November 9, at 3:35 AM MST.^[2] Since ISM Raceway is under 1.5 miles (2.4 km), the qualifying system was a multi-car system that included three rounds. The first round was 15 minutes, where every driver would be able to set a lap within the 15 minutes. Then, the second round would consist of the fastest 24 cars in Round 1, and drivers would have 10 minutes to set a lap. Round 3 consisted of the fastest 12 drivers from Round 2, and the drivers would have 5 minutes to set a time. Whoever was fastest in Round 3 would win the pole.^[4]

Noah Gragson of Kyle Busch Motorsports would set the fastest time in Round 3 and win the pole with a 26.456 and an average speed of 136.075 miles per hour (218.991 km/h).^[5]
