Exhibit 99.7

DRIVER SUPPORT FAQ

What was announced?

Swift Transportation and Knight Transportation have entered an agreement to operate under common ownership. The Swift holding company will be renamed Knight-Swift Transportation Holdings Inc., and the common ownership structure will enable both companies to share best practices, while running the businesses independently and maintaining separate brands. There is no immediate impact in how we do business and we will continue working toward building our brand and realizing our vision.

Richard Stocking and Ginnie Henkels have chosen to pursue other opportunities following the close of the transaction though will stay on until then to ensure a seamless transition. Once the transaction is completed, which we expect to occur in the third quarter of 2017, the combined company will be led by Dave Jackson as CEO and by Adam Miller as CFO, with. Kevin Knight serving as the Executive Chairman. Knight’s Executive Chairman, Kevin Knight, will assume the role of President of Swift (which will operate as a subsidiary of the combined company post-closing) and Knight’s President and CEO, Dave Jackson, will remain President of Knight (which will also operate as a subsidiary of the combined company post-closing.)

How long will all of this take?

We anticipate the transaction to close in the third quarter of 2017.

How does this transaction fit with Swift’s strategy?

Both companies will continue to run their businesses independently and will maintain their separate brands. Bringing together these two long-standing, industry-leading trucking companies means increased scale and a combined strength of resources.

Knight’s dynamic leadership team is committed to the same principles and level of integrity that we live by every day, and we have the utmost confidence that together with the Swift leadership team you know well, we will continue working toward our vision.

How will executive leadership change?

Richard and Ginnie have chosen to pursue other opportunities following the close of the transaction, though will stay on until then to ensure a seamless transition. Once the transaction is completed, Kevin Knight, current Executive Chairman of Knight Transportation, will assume the role of President of Swift (operating as a subsidiary of the combined company).

Will we run two separate Accounting/Operations/HR/etc. departments?

As both companies will be separately operated redundancies are necessary to continue serving drivers and customers with excellence. For the next 3-4 months, the Knight-Swift Transition Planning team will evaluate how to best to maintain these distinct brands while sharing best practices and capitalizing on economies of scale where possible.

What will happen with my outstanding equity awards?

Each stock option, restricted stock award, restricted stock unit award, and performance share award that is outstanding prior to the transaction will be adjusted to correspond to the converted Knight-Swift common stock. The closing of the transaction will constitute a change in control under the Swift equity plan and Swift equity awards.

Holders of vested Swift stock options will be able to exercise their options into Knight-Swift Common Stock, with an adjusted exercise price that corresponds to the Knight-Swift common stock. Holders of Swift restricted stock awards will hold Knight-Swift common stock as of closing of the transaction. All Swift equity awards will remain subject to the terms and conditions of the applicable award agreements and Swift equity plan following the closing of the transaction.
