Using European naturalistic driving data to assess secondary task engagement when stopped at a red light

To text or not to text – drivers' interpretation of traffic situations as the basis for their decision to (not) engage in text messaging

“…Also, it should be pointed out that, even though participants’ selection and description of ‘appropriate’ contexts for texting appears to be somewhat reasonable, it is questionable if they would be able to finish the text message within the same context.
