## 4 Results of Surveys  
One of the first questions asked by the respondents was the knowledge of the provisions of the Road Traffic Law about the use of a mobile phone while transmitting a red signal (waiting for a signal that allows traffic). 56% of the respondents gave an affirmative answer: the driver must not perform this activity without a headset, 29% of them were convinced that this behavior is not inconsistent with applicable regulations, while 15% were unable to answer (marked \"I don't know\"). The next question was a request to state the frequency of using a mobile phone while traveling by car. The results obtained are as follows:  
* always--7%,
* often--21%,
* from time to time--26%,
* rarely--38%,
* never--8%. It is noteworthy that although over 50% of the information about the current ban on using the telephone while driving was found, over 90% of the respondents declared that they would perform this activity while traveling. Then, the respondents were to supply the manner of using the telephone by the respondents in case of stopping the vehicle at the intersection entrance while waiting for a green signal. The respondents said that the mobile phone they use in such a situation is:  
* mounted on a special holder--55%,
* hand-held--40%,  
or otherwise used--5% (e.g., smartwatch worn on the wrist or steering wheel). The main reasons for using a mobile phone while traveling in a motor vehicle, given by the respondents, are presented in Figures 1 and 2--as a driver or as a passenger, respectively. The most frequently chosen responses among those mentioned by drivers were: continuation/starting a voice call (57.65%), changing music (48.53%), and replying/starting SMS (34.97%). Much fewer people say that they use a telephone to enter voice commands (15.52%) and search for information (8.84%). A slight percentage of the respondents chose to read the content of mobile media (3.14%), look at the status of other social profiles (2.95%), watch a movie/series (1.38%) or play (0.98%). Only one person listed making/continuing online purchases and updating status on a social networking site. Moreover, 12.38% of the respondents replied other, of which the use of navigation accounted for approximately 90% of these responses. The indicated reasons for using the telephone during the journey as a passenger are presented in Figure 2. Most people believe that they use the telephone to reply/start texting (71.12%). In turn, more than half of the respondents \"simply\" look for information (55.21%) and read the content of mobile media (49.31%). Almost half of the people said that they change their music (43.61%), continue/start a voice conversation (42.24%), and look at the status of other people on social networks (37.13%). About 15% of respondents say that they use a phone to play games and continue shopping online. The smallest percentage of respondents chose to update their status on a social networking site (7.47%), watch a movie/series (8.64%), and enter/continue voice commands (3.34%). Moreover, 1.18% of the respondents replied other, of which the use of navigation accounted for almost 90% of these responses. The rest of the respondents use the telephone to check the time. Figure 3 shows the purposes of using a mobile phone by drivers, but only during the waiting period for a green signal at the entrance to the traffic light intersection. The responses supplied show that the most often performed activity by drivers is texting them (51.47%). Next is changing the music (40.47%) and continuing/starting a voice conversation (37.33%). A much smaller percentage of respondents is looking for information (10.61%), introducing voice commands (8.84%), looking at the status of other people on social networks (6.68%), and reading electronic media content (5.50%). Only 1.38% of respondents use mobile games, 0.59% update their status on a social network, and 0.79% do/continue online shopping. Only one person said that they were watching a movie/series at that time.
