Do I Need to Tip a Limo Driver? Before paying a limo driver call the limo company and ask them if gratuity is included in the bill. If the limo driver did his job then tip him a 15% to 20% of the total bill. If the limo service was poor, then tip the limo driver 5% or lower of the total bill. At minimum, a limo driver should be paid around $5-10 for short trips, regardless of the percentage.
