Mack Trucks is now accepting entries for its 2026 calendar contest, continuing its annual tradition of showcasing customer-owned trucks in revenue operation across North America.

Twelve trucks will be selected to appear in the upcoming calendar, each receiving a professional photo shoot organized by Mack. The contest is open through April 30, with public voting taking place during the same period, starting April 1.

Eligible entries must be Mack models currently in revenue service — collector and antique trucks are not permitted. The voting categories align with Mack’s lineup, including the Anthem, Granite, Pinnacle, TerraPro, LR, LR Electric, MD, and MD Electric, as well as a legacy category for out-of-production models still working in the field.

“We received a record 432,000 votes for the 2025 contest, which demonstrated the incredible passion of the Mack community,” said David Galbraith, vice-president, global brand and marketing, in the news release. “The 2026 calendar will continue our celebration of Mack’s remarkable heritage and the hardworking customers who keep our trucks on the road.”

This year’s contest includes several enhancements aimed at boosting participation. Contestants who enter before April 1 will receive 125 bonus votes, and those who submit a video along with their truck photo will earn another 125, giving them a 250-vote head start. Mack will also announce Bonus Vote Days through its social media channels, when daily votes may count for double or triple.

Participants are encouraged to share their entries using #MackCalendarContest to increase exposure, and all entries will be eligible for promotion to Mack’s audience of more than 900,000 followers.

“The competition grows more impressive each year,” Galbraith added. “We’re excited to see the entries for 2026 and to continue the tradition of featuring our customers’ working Bulldogs in this popular calendar.”

Winners will be contacted by phone or email by mid-May and announced on Mack’s social media platforms by May 30.
