Colorado CDL Requirements

Known as The Centennial State, Colorado encompasses most of the Southern Rockies. It is the 21st most populous in the USA and the eighth largest. It is bordered by Wyoming to the north, New Mexico to the south, Kansas on its eastern side and Utah to the west. The state's name comes from the Spanish meaning "colored red". The state is not red, but its primary river (also called Colorado) is thick in silt, giving it a red hue. The climate of Colorado consists of three general zones: the eastern plains, the foothills and the mountains. To the south is the Rio Grande headwaters and desert while heading north leads to the Rocky Mountains. It's certainly a state of contrast with largely an upland climate. It's the only state whose elevation does not fall below 1,000m. Its lowest point sits at 1,011m (3,317ft). By becoming a truck driver in Colorado you'll be driving within some of the most beautiful displays of nature the world has to offer.

Colorado CDL Salary, Employment, and Prospects

BLS data released in 2017 based on 2016 data reports a low to moderate availability of CDL roles of any class. Growth is expected to be around 5%, slightly under the national average of all jobs. The reasons are numerous, partly down to efficiency and partly down to cost - other methods of transport may prove cheaper in the long-run for transportation of mass haulage (rail, air) and the rise of independent transport for lighter vehicle transportation and GPS technology means lower growth.

Heavy Trucks

According to 2017 data, the mean salary for all heavy truck drivers is $41,340. The equivalent hourly pay rate is $19.87. The average salary in Colorado is considerably higher than the national median at $47,340. Median hourly pay is $21.91 and the mean hourly pay is $22.76. The lowest 10% salary according to 2016 statistics was $26,920. The highest 10% salary band was reported at in excess of $63,140.

Light Trucks

The mean salary for this type of role is slightly lower than heavy trucks. Averages are $34,790 (mean salary) and $16.73 (mean hourly). The situation in Colorado with regard to light trucking is similar to heavy trucking. Light truck drivers in the state can expect a mean salary of $37,240 and hourly pay of are $16.56 (median) and $17.90 (mean). Delivery drivers, vans and small trucks employment is projected to grow 4% to 2024. This is nearly half the national average. Advances in e-commerce planning means fewer drivers and greater efficiency.

Passenger Vehicles

The average salary for all bus drivers and passenger vehicles is $31,920. The equivalent hourly rate is $14.96. As with the other two classes, passenger vehicle drivers can expect a higher than average rate of pay for both hourly and salaried jobs. In Colorado, the average salary is $36,430. The equivalent hourly pay is $17.55 (median) and $17.52 (mean). We expect job demand to grow some 6% between 2014 and 2024 - the national average for all jobs.
