Many chauffeur companies ask passengers to sign a service agreement before the first confirmed trip. It covers things like waiting time, damage, and their cancellation terms.
- Open the link in the email asking you to sign.
- Read the agreement.
- Sign on screen with your finger or your mouse and submit.
That is a one-off. You are only asked again if your company updates its terms. If you have not signed by the time your driver arrives, they can take your signature on their phone instead — it will not hold up the trip.
