If the position in question requires travel, it will likely mention in the job posting. If you applied, knowing that some trips were needed, then - of course, you are okay with travel! But before blindly agreeing to any travel, you can ask the interviewer the percentage of travel expected in the role. Be sure to clarify day trips versus overnight travel. If you have limitations, this is the time to bring those up.
"I did see that there is some overnight travel in this role. Could you clarify for me what percent of the month I would spend on the road?"
"Although I have never traveled for work, I do not have any personal circumstances that would get in the way of the odd travel request. Could you share with me more details on these potential travel needs?"
"Currently, I manage two warehouses which require some day travel from me, twice per week. I am completely comfortable with travel for work. Could you provide me with more details on your travel needs such as locations, and amount of time spent on the road?"
"I have traveled for conferences and larger client meetings. As long as the requests are in enough notice to make personal arrangements, I am more than happy to accommodate. Could you give me an example of the average travel time for this role?"
"I am willing to travel, yes. I think it would be great to visit other locations and get to know your team across the state. Any additional details you have on the travel requirements would be helpful."
"As a seasoned sales professional, I refer to myself as a 'road warrior!' I am on the road, with overnight travel, about 60% of the time. With that said, I would like to cut back on that a touch. When your job posting mentioned about 40% overnight travel, I thought that was perfect."
"Teachers do not travel too often, so I certainly welcome the opportunity whether it's to assist when your athletic teams make nationals or to attend education-related conferences. Some notice is, of course, appreciated - but I will always do what it takes to succeed in this role."
"I travel from site to site on a daily basis in my current role. I am very used to it and quite enjoy that part of my current position."
