As Arctic conditions continue NHS Tayside has warned residents only to go out if necessary.
The health board has seen a "sharp rise" in the number of people attending its A&E departments at Perth Royal Infirmary and Ninewells after falling on ice.
On Monday temperatures plummeted below zero to as low as -8ºC in Strathallan creating treacherous conditions for those venturing outside.
The Met Office has forecast the cold spell to continue this week and an NHS Tayside consultant has warned residents to "take extra care" and "only to go outside if it is necessary".
Emergency Department consultant and clinical lead for Winter Planning Dr Andrew Reddick said: "We have seen a sharp rise in the number of people coming to our A&E departments as a result of falling on ice.
"Our advice would be only to go outside if it is necessary and to take extra care when walking on icy roads and pavements. Please grit your driveways and paths. Anyone venturing outside should wear appropriate shoes with a good grip and several thin layers to help keep warm along with a coat, hat and gloves."
Dr Reddick also reminded Perth and Kinross residents not to go straight to A&E unless it is a life-threatening condition.
He said: "If people fall and think they need to go to A&E, it is important to remember that the way people access A&E services has changed.
"To ensure you get the fastest access to the treatment you need, anyone with a non-life threatening condition should call NHS 24 on 111 first, day or night, to be directed to the right NHS service.
"If you think you need A&E, but it is not an emergency you can contact NHS 24 where you may be referred on to the virtual A&E for a telephone or video consultation with a senior clinical decision maker.
"You will get treated faster, and if you do need to visit a physical site for an in-person consultation, you may receive an appointment to help avoid any unnecessary waits in A&E."
Perth and Kinross Council has warned drivers the freezing temperatures can actually prevent the grit from taking effect. On Monday PKC warned motorists - via its social media platforms - to "drive with extra caution".
The post said: "Did you know that despite being most needed in the cold weather low temperatures can actually prevent grit from taking effect? Really low road surface temperatures forecast this week mean the grit will take some time to have any effect. Please drive with extra caution."
A PKC spokesperson added: "Effectiveness of the salt reduces the colder it gets and also needs you to work it into the snow and ice to start that chemical reaction."
The council is also keen to remind anyone impacted by the cold weather of its warm spaces.
A PKC spokesperson told the Perthshire Advertiser: "With more funding towards community warm spaces and warm packs agreed by the Finance and Resources Committee recently we’re continuing to update the warm spaces map on our website with details about new places for people to go for a warm welcome and a cosy space to spend some time if they’re worried about heating costs at home: https://www.pkc.gov.uk/warmspaces."
The cold spell looks set to continue this week.
Met Office Chief Meteorologist Matthew Lehnert said: "The cold conditions will remain in situ during this week. In many places daytime temperatures will struggle to get above freezing, while overnight temperatures have the potential to drop below -10 C in rural parts of Scotland."
