Best way to survey freight companies about tech adoption?

For freight companies, I'd actually combine both — start with 8-10 in-depth interviews with fleet managers or ops directors to nail down the right language and decision factors, then build a structured survey (SurveyMonkey or Qualtrics work fine) to validate at scale. These folks are busy, so keep surveys under 10 minutes and consider a small incentive like a $25 Amazon card to boost response rates.
