A toll relief scheme in New South Wales will expire on Friday, but Service NSW says 100,000 eligible drivers still have not claimed their discounts, 9News reports. Drivers who paid $877 (US$579) or more in tolls the previous financial year can claim a half-priced vehicle registration for one year. Drivers who paid $1,462 (US$965) or more can get free vehicle registration. The arrangement is being phased out in favor of a cash-back program.
