Ben Green, 23, of Aintree Drive, Waterlooville, appeared at Portsmouth Crown Court facing two charges.
He denies causing 80-year-old John Dognini's death by careless driving, and causing his death while driving uninsured.
Police previously said Mr Dognini was riding a mobility scooter out buying Christmas presents for his grandchildren and great-grandchildren in December 2019 when the crash happened.
Police were called to the junction of London Road and Winifred Road, Waterlooville, on December 2. Mr Dognini died days later after the crash.
He had been due to celebrate his 60th wedding anniversary with his wife Julia in March last year.
Judge Timothy Mousley QC bailed Green, dressed in a suit and tie, to appear for his four-day trial on September 20.
Previously Mr Dognini's family said: 'Our world changed forever on Monday, December 2 (in 2019), when our darling John was involved in a horrific incident.
He was on his way to buy Christmas presents for all his grandchildren and great-grandchild.
‘His Christmas was just beginning.’
The family statement continued by calling him a ‘loveable husband’ and a ‘caring, amazing father’.
‘John was infectious and anyone that ever had the pleasure to meet him was blown away by his kindness, love and passion for life,’ they added.
‘The hole that is left will never be filled but as a family we know that our darling John would want us to love life as much as he did.’
