Isle of Wight Council bosses have overturned a vote by councillors - who had rejected the partnership to secure £900 million of funding.
Hampshire Areas Trialling 20MPH Limits
Hampshire County Council is to trial 20 mph speed limits in ten locations across the county.
The council says the pilot schemes are are in response to requests from residents, and the total cost for implementing the trials will be in the region of £250,000.
The first schemes are expected to be implemented in the Spring, once they've consultated with residents to make sure they support the move in each area.
The ten recommended locations for the pilot schemes are:
Medstead, East Hampshire
Cherbourg Road (and surrounding roads), Eastleigh
Wallington Village, Fareham
Clarence Road, Connaught Road, Albert Street and Albany Road area, Hart
Hythe, New Forest
Farnborough Old Town Area, Rushmoor
Hayling Island, West Town, Havant
Floral Way, Andover
Councillor Mel Kendal, Deputy Leader and Executive Member for Environment and Transport, said:
"For the pilot schemes to be successful, it is essential that local people support the introduction of 20mph speed restrictions.
"In the Autumn we will be sending residents in the ten locations a questionnaire to complete and return it to us, so that we know the views of local people.
"Department for Transport guidance states that generally, 20mph speed limits should be self enforcing.
"The police are unlikely to treat enforcement as a priority in the residential 20mph areas and so we will need the support of residents through their participation in Community Speed Watch programmes."
The 20mph speed limits will be indicated in the pilot areas using road side signs and 20mph road marking.
Residents will be encouraged to help promote awareness of their 20mph speed limit via a publicity campaign. "Before" and "After" speed monitoring will be carried out in a sample of roads in each area to assess the impact of the new speed limit.
The busy road's being made two lanes in both directions between Segensworth and Titchfield - it's due to take 18 months.
